Two books, two authors, two international locations bursting with neotropical avian range. Birds of Belize by Steve N. G. Howell and Dale Dyer and Birds of Costa Rica by Dale Dyer and Steve N. G. Howell joined the sphere information roster this spring, very welcome in a 12 months sadly sparse in new titles. Because the books share authors and a creation course of, I believed I’d evaluate them collectively. Each titles are superlative guides to 2 well-liked birding locations, that includes detailed but succinct up-to-date descriptions, magical scientific illustrations, and the well-crafted organizational options by now anticipated from Howell, certainly one of our most prolific chook ebook writers and a vocal proponent of user-friendly guides. But in addition they convey up questions, which I’m going to speak about proper now earlier than diving into the specifics of the guides themselves.

Two points got here to thoughts instantly after I examined my reviewer copies. The primary is that the illustrations by Dale Dyer are based mostly, and largely appear to be the identical, because the illustrations for his earlier information Birds of Central America: Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, and Panama (co-authored with Andrew Vallely, PUP, 2018). It’s not clear how lots of the plates have been touched up, redrawn or are new, and I hope we’ll study extra in regards to the course of, maybe when the third ebook within the sequence by Howell and Dyer, a brand new information to the birds of Mexico, is printed.* An related situation is that the Belize and Costa Rica guides share lots of the identical descriptions of species, written by Howell.

Why are these points? I believe as a result of we, or at the least I, have a fantasy of each area information being created distinctive and new, that after I gently carry the duvet a brand new information, I’ll discover treasures we’ve by no means seen earlier than. Fantasy is the important thing phrase right here. If we would like new area guides, we have to admit that it’s not economically or humanly potential to attract and paint a brand new Clay-colored Thrush for every title. Doing this work takes time! Dale Dyer put in years engaged on his work for Birds of Central America, each within the area and within the museum. I don’t suppose scientific paintings holds much less worth when used greater than as soon as. Equally, descriptions of species repeated throughout volumes don’t lose their accuracy with every publication. Steve Howell has spent many years of expertise within the area learning the birds of Belize, Costa Rica, and particularly Mexico. There isn’t any cause experience and expertise can’t be shared throughout area guides when the books are printed shut collectively, like these are. I believe we do have the appropriate to count on that paintings and species descriptions when repeated are present, replicate latest research and taxonomic thought. And I believe these guides do, that the authors will not be simply rubber-stamping their work however have sought to ensure the paintings and textual content in every information represents the birds of every nation.

The second situation entails taxonomy. Howell makes use of the IOC World Chook Record (v.11.2, 2021) as his “baseline taxonomy” after which makes adjustments, plenty of adjustments. For oceanic birds he makes use of the taxonomy that he and Kirk Zufelt developed in Oceanic Birds of the World: A Photograph Information (PUP, 2019).  Different species are splits and lumped and have had their names modified. Not each chook. A lot of the names right here shall be acquainted to the skilled Neotropical birder. However Howell has robust emotions about what makes a species and what proof helps splitting or lumping a species and he applies them, in some instances coining his personal widespread names. Tropical Kingbird is “Center American Kingbird,” based mostly on the concept good ol’ TK needs to be divided into three species based mostly on track, morphology, and plumage. Southern Lapwing is “Cayenne Lapwing,” cut up from “Chilean Lapwing.” Willet is listed as “Western Willet” and “Jap Willet,” two separate species, one thing we’ve anticipated from the North American Classification Committee for a few years, however which has not but handed committee muster. American Herring Gull is “Smithsonian Gull,” a separate species from its European counterpart. And Sandwich Tern is Sandwich Tern, Howell discovering the DNA analysis for splitting it “weak.” These are just a few examples. The introductory part “Taxonomy” summarizes the authors’ strategy to this course of in each guides and prolonged appendix sections entitled “Taxonomic Notes,” clarify particular species adjustments.

Why is that this a problem? Taxonomy and classification programs for any space of data, not simply ornithology, are historically developed, written, and accredited by committees and networks of specialists with levels and titles of authority. I ought to know, as a librarian I used to be taught to worship classification programs like LCC, the Library of Congress Classification system which divides data into 21 fundamental lessons, and topic heading authority lists. In birding, we’ve got a number of increased authorities–the AOS Guidelines of North and Center American Birds; the AOS Guidelines of South American Birds; the Clements classification system, which is the idea for eBird; the IOC World Chook Record; and the guidelines developed by Handbook of the Birds of the World and Birdlife Worldwide. And when writing a area information, it’s accepted apply to undertake one of many above and to stay to it, with any questions or disagreements safely ensconced within the textual content, not in an precise change of species.

Howell turns all that on its head. The idea of species, he states, “mainly comes right down to a matter of opinion, with no proper or incorrect” (CR information, p. 30). And as for who has the authority to make taxonomic selections, he and Dyer argue of their associated article in North American Birds, “Costa Rica: Even Richer Than we Thought?”(a must-read for birders who shall be utilizing these guides and who wish to know extra about their growth) that “individuals who research a area and are acquainted with its birds are sometimes higher positioned to make knowledgeable taxonomic selections than distant our bodies coping with a lot bigger geographic areas.”** Howell additionally states that there isn’t a higher place than a area information wherein to introduce taxonomic adjustments, one thing he’s been doing since he and Sophie Webb wrote their information to Mexico and Northern Central America within the 1990’s.*** It’s quicker than committee work, extra direct than forms, and it presents a clearer and extra full portrait of the vary and worth of the biodiversity of those international locations. “We hope that drawing consideration to them [the splits] acts as a laxative on the taxonomic constipation manifested by some committees and speeds the speed at which ignorance and inertia fall sufferer to actuality” (CR information, p. 30).

These are convincing, well introduced arguments. However I can’t assist fascinated with the person birder utilizing these area guides, particularly a birder new to Neotropical birding. I believe it’s complicated to see Center American Kingbird within the area information however not in eBird. I don’t suppose it’s useful to have Herring Gull introduced as “Smithsonian (American Herring) Gull.” I don’t suppose each birder desires to take the time to learn taxonomic notes and take into consideration the 100-plus splits proposed by Howell and Dyer. (I’m not saying that is proper, I’m saying, as somebody skilled in utilizing reference books with individuals looking for a selected reply, there’s a restrict in how a lot preparatory time they’re prepared to place in.) In presenting a area information with different taxonomy and names, the authors could also be jumpstarting “official” adjustments in taxonomies and birding checklists, however they could even be incorporating obstacles in these books; area guides are presupposed to be making birding and chook identification simpler, no more complicated.

I don’t suppose it is a black-and-white situation and I’m hoping readers of this evaluate have their very own opinions that they may articulate right here or on ‘the socials.’ And maybe one other 10,000 Birds reviewer could have a special viewpoint.

Protection & Group

Birds of Belize covers 540 or so species (I counted, the press launch says “over 500”) commonly present in Belize, together with the islands of the barrier reef and marine waters about 30 miles out, the vary of a day journey. Along with species commonly occurring in Belize, migrant and resident, the Species Accounts part additionally consists of a number of rarer occurring species. Some, like American Bittern, are allotted full accounts; others, like White-faced Ibis, are cited and drawn to tell apart them from similar-looking species (in some instances, as with White-faced Ibis, there’s a risk that they could have been neglected). Appendix A lists “Uncommon Migrants and Vagrants,” 81 species, together with birds for which there are not any documented data, however that are listed within the literature or eBird. For context, the IOC model 13.1 Guidelines for Belize lists 622 species in 76 households, of which 104 are uncommon or unintended and 4 launched.

Birds of Costa Rica covers 836 commonly occurring and a few rarer species discovered on the mainland, inshore islands, and waters about 30 miles out. “Offshore Guests, Uncommon Migrants, and Vagrants,” 103 species together with a number of seabird species, are listed in Appendix B. The birds of Cocos Island, an remoted, volcanic island with a wealthy chook life, are listed in one other Appendix part. That is spectacular protection of a rustic that boasts over 950 avian species (the IOC model 13.1 Guidelines lists 955 species in 86 households, with 152 uncommon/unintended species, three extirpated species, 5 launched species, and 9 endemics).

The books are flexibound, with back and front flaps. The entrance flaps supply helpful keys to the species vary maps (see picture above), the again flaps supply all–too-brief bios of the authors (I need extra!). The within entrance covers are the beginning of four-page pictorial guides to chook households/teams and the pages the place they are often discovered, a fast, straightforward entry to the identification course of (see picture above). I notably like the way in which some chook households, like Antbirds and Tanagers, present groupings of a number of completely different species, representing the number of shapes and colours present in that household.

Entrance of the ebook materials consists of: “Preface and Acknowledgements,” helpful for its abstract of the authors’ backgrounds in Belize and Costa Rica in addition to acknowledgement of earlier works; a succinct information on “How To Use This Guide” (please learn!); three drawings illustrating “Chook Topography;” a brief listing of “Abbreviations and Some Phrases Defined;” a piece on habitat and local weather titled “Biogeography;” and the must-read feedback on “Taxonomy” (titled “Taxonomy and Names” within the Belize quantity although it’s mainly the identical essay however with out the quotation of the Birding article). The “Biogeography” sections are largely pictorial, that includes massive images. Within the Belize quantity, they have been taken by H. Lee Jones, creator of the earlier chook information to Belize. The few pages of textual content pack in loads of info on geographical location, formations, waterways, local weather, varieties of forest and wetland habitats and the birds prone to be present in them, however the textual content doesn’t relate to the images and the data is a bit squashed collectively. Nation maps are separated out –political maps are within the “How one can Use This Guide” part and geographical maps are within the “Biogeography.” I actually want they’d been duplicated within the again inside covers, that are clean.

Again of the ebook sections embody Appendices on “Uncommon Migrants and Vagrants;” “Taxonomic Notes;” and within the Costa Rica ebook, a piece on “Cocos Island.” There’s additionally a list of “References” and an “Index of English Names.” These are fascinating decisions. The references are books the authors used to create the guides, a mixture of area guides, ornithological articles, and checklists, not a recommended supply of studying for the birder utilizing the ebook. I’m not saying that is good or dangerous, I do respect the cautious documentation of the taxonomic notes and different supplies. I’m shocked by the absence of a scientific identify index, particularly in a world that’s advocating altering English names and by Howell’s personal use of different names for some species. Fortunately, all names–daring listed and different–are listed within the index; there are web page references for Smithsonian Gull and Herring Gull. I’m additionally very blissful that the index teams birds by “final identify;” all of the trogons are below “Trogon,” all of the warblers whose identify consists of “warbler” are below “Warbler” (Parulas, Redstarts, and Waterthrushes have their very own entries).

Measurement-wise, these books are of a dimension that will match effectively right into a backpack or a big vest or coat pocket. The Costa Rica ebook is way thicker and heavier (extra birds!), and at about 2 kilos in weight could be for a few of us a automobile ebook reasonably than a backpack ebook.

Species Accounts

Textual content on the left, illustrations on the appropriate. The Species Accounts observe the ‘trendy information’ format, with illustrations clearly labeled and organized in species groupings. The Accounts make the most of the “user-friendly” area information sequence proposed in “The Objective of Subject Guides: Taxonomy vs. Utility” by Howell and 5 different notable birding authors (Birding, 2009^). It begins with water and wading birds and ending with meadowlark, blackbird, and bobolink.^ No matter whether or not you suppose area information sequences ought to or mustn’t replicate present evolutionary sequence, it’s comforting and simple to search out falcons subsequent to hawks, vireos subsequent to warblers.

The textual content is remarkably straightforward to learn, thanks partially to a extremely readable font, color-banded household and genera sections, bolded and capitalized species names and part labels, and simply the correct amount of area between species descriptions. Even pages that cowl 5 completely different species don’t appear crowded. Every household part begins with a quick encapsulation of what sort of birds are in that household, their widespread traits and the variety of species in that exact nation; some genera descriptions are additionally given. That is notably useful for chook households that could be new to birders. I do know I’d have benefitted from studying the summaries on the Typical Antbird household (Thamnophilidae) and its member teams: Antshrikes (with stout, hooked payments), Antvireos (chunky birds with pretty stout payments, like vireos), Antwrens (small, arboreal birds with slender payments), and ‘Skilled’ Antbirds (“boldly patterned” antbirds which can be severe followers of military ants).

Every species account begins with the English identify and scientific identify. Quite a lot of consideration is positioned on names, reflecting the authors’ precedence on previous and present taxonomy. Alternate names are given in parentheses: Smithsonian (American Herring) Gull. Associated names are given in brackets: Lesson’s [Blue-crowned] Motmot. Bracket names embody former names for species which were cut up (the Motmot) and different situations the place taxonomy is “unsure.” Measurement–size and typically wingspan–is given in centimeters. Subsequent is the part birders are most definitely to learn first, a abstract of the chook’s habitat, conduct, and figuring out options: the place and the way it’s prone to be seen (humid forest, fast-flowing streams, plantations, excessive, low, with blended flocks, alone and quiet), vital conduct (heard greater than seen, flushes, sallies for bugs, soars on flattish wings, flight fast and darting), and find out how to distinguish it from related birds within the space. This part additionally particulars vital plumage options for the grownup chook and for the juvenile and feminine is required.

Sound is subsequent: descriptions and transcriptions of vocalizations, together with cadence, repetitive sounds, and species that sound related. The Standing part is supposed for use with the distribution maps. The textual content signifies if the chook is a winter, summer season, or nonbreeding migrant (resident is the default standing) and at what elevation it’s prone to be discovered. The maps, that are positioned to the left of the textual content, are small and point out major seasonal standing–whether or not and the place the chook is a resident breeding species, seasonal breeding migrant, seasonal nonbreeding migrant, or transient migrant. Additionally they sometimes present breeding colonies or remoted populations, potential occurrences, and instructions of vary enlargement.

I like the writing right here. It is extremely particular and really detailed. There’s little room for a wise flip of phrase, however the exactitude of each sentence makes every account distinctive and relevant to chook identification within the area. Lengthy-billed Hermit is, “A spectacular if dull-plumaged hummer of humid forest understory…” (CR, p. 212). Bat Falcon is a “Good-looking small falcon of humid forest and edge, adjoining clearings, semi-open areas with scattered bushes and forest patches; domestically in cities, typically at Maya damage websites” (Belize, p. 116). I used to be blissful to see that the outline within the Costa Rica information is comparable however drops the reference to Maya ruins, a element that tells me every information was fastidiously curated for its nation. Keel-billed Toucan provides a “Loud throaty croak…at a distance feels like frogs…up shut has an ear-splitting, shrieking high quality” (CR, p. 200). Maybe the perfect examples of Howell’s experience at writing species descriptions are the pages on these brown rainforest look-alike birds, the Woodcreepers. He distinguishes every by consideration to foraging conduct, high-quality variations in invoice dimension and coloration, and vocalization. Southern Noticed Woodcreeper has a “pretty stout straight invoice extensively darkish above” (p. 248), Northern Barred Woodcreeper has a “stout blackish invoice with pinkish base” (p. 246), whereas Ivory-billed Woodcreeper’ invoice is “not strikingly ivory-colored, typically dusky pale pinkish total, typically with a darkish maxilla” (p. 248).

[There is one error in the Belize guide which is pointed out by a user on the Amazon page: the images of White-whiskered Puffbird are reversed, with the female labelled male and male labelled female. This is corrected in the Costa Rica guide.]

Writer Steve N. G. Howell has a protracted listing of chook and birding books to his credit score, a number of of which have been reviewed right here. Along with the already talked about A Information to the Birds of Mexico and Northern Central America, co-authored with Sophie Webb (1995) and Oceanic Birds of the World: a Photograph Information, co-authored with Kirk Zufelt (2019), his titles embody Petrels, Albatrosses, and Storm-Petrels of North America: A Photographic Information (2012), A Reference Information to Gulls of the Americas (with Jon Dunn, 2007,  Molt in North American Birds (2010), Uncommon Birds of North America (with Ian Lewington and Will Russell, 2014), Offshore Sea Life ID Information: West Coast (with Brian L. Sullivan, 2015), Offshore Sea Life ID Information: East Coast (with Brian L. Sullivan, 2016), Birds of Chile: a Photograph Information (with Fabrice Schmitt, 2018), and Peterson Information To Chook Identification in 12 Steps (with Brian Sullivan, 2018). He has additionally printed many scientific articles on these matters in ornithological journals and articles and weblog posts on taxonomy, writing area guides, and birding for well-liked birding magazines and web sites. Howell has additionally been a chook tour chief with WINGS for a few years, the place he focuses on excursions of Mexico, Central American international locations, and repositioning cruises.

The illustrations by Dale Dyer completely complement Howell’s descriptions. A birder in addition to a scientific illustrator specializing in birds, Dyer is a area affiliate on the American Museum of Pure Historical past and has contributed work and drawings to a variety of area guides, together with books on Puerto Rico, the West Indies, Brazil, Trinidad and Tobago, Peru, North America, and New York State. Dyer spent a few years engaged on these illustrations; the Preface notes that he visited Costa Rica and different Central American international locations yearly between 2007 and 2016. He additionally utilized museum specimens and speaks eloquently in interviews and on his site in regards to the significance on beginning every chook drawing with a research of skins to know the construction and anatomy beneath the feathers.^^

Quite a lot of thought clearly went into the design in addition to the paintings itself. Every plate illustrates two to 5 species, akin to the textual content on the alternative web page. One to 4 pictures of every species are depicted, relying on the species; female and male Contingas are pictured within the examples above, White-rumped Sandpiper is proven in breeding, non-breeding, and juvenile plumages plus a picture of it in flight. All raptor and nightjar species are proven in flight, typically in a number of pictures, aside from the tropical forest accipiters and forest falcons (maybe as a result of they’re hardly ever seen?). All plumage variations are clearly labelled. Often, we get behavioral vignettes just like the Central American Sharpbill above, probing a leaf cluster. Species are fastidiously grouped on every plate so it’s straightforward to see which pictures are the identical species, and when two genera or households share the identical plate, Dyer very properly has them posing in reverse instructions so we all know they’re completely different.

The photographs themselves, other than their utility as identification aids, are merely lovely. They’ve been painted, I assume, with the watercolor/gouache technique utilized in Dyer’s different works. Feathers glow with the subtlety of sample and shade of colours that distinguish chook life. Payments level, claws grip, eyes glower. Every particular person portray actually does appear to be a person chook. In my evaluate of Birds of Central America, I wrote that I believed the colours have been washed out on some birds. I don’t suppose so with these volumes, and I’m unsure if my eyes have gotten accustomed to Dyers’ work or if there have been some adjustments within the inking. The birds have been drawn and painted on backgrounds of various shades of grey/blue, gentle blue, peach, ecru, tan/brown, and many others. This works properly to boost the inking and relieve the attention of continually a white background, and on one pleasant plate creates the energetic picture of standing egrets towards a pale greige background counterpointed with flying egrets and a juvenile Little Blue Heron flying towards a sky-blue background. The background does appear slightly too darkish on some plates, nevertheless, and although one can say this represents how the birds are seen in the dead of night rainforest, it does make it troublesome to review the species in lower than brilliant gentle.

I believed it will be fascinating to check how one species is painted and configured on the web page within the three books illustrated by Dyer and by two different area guides: The Birds of Costa Rica: A Subject Information, 2nd ed., written by Richard Garrigues and illustrated by Robert Dean (Comstock, 2014) and Birds of Belize, written by H. Lee Jones and illustrated by Dana Gardner (Univ. of Texas Press, 2004). These signify, I believe, the sphere guides used essentially the most typically earlier than publication of those volumes. I made a decision to have a look at depictions of Pretty Continga, a sought-after species in Belize and Costa Rica. Pretty Cotinga males are a spectacular blue and purple and the females are a spectacular brown and beige, so it is a good solution to see how the artists painting each ends of the chook “magnificence” scale. The plates for the 2023 guides are above, the others beneath.

Dyer’s paintings for the Birds of Central America information is completely reproduced within the Belize and Costa Rica volumes, right down to the little portrait of the male perched on a leafy department. The primary distinction is that “male” and “feminine” are spelled out. The illustration by Dana Gardner for the 2003 Belize information is extra coloration blocked, much less refined, a completely completely different type. The Pretty Cotingas illustrated by Robert Dean for the 2014 Costa Rica information are chunkier with rounder heads, additionally extra coloration blocked. All good illustrations for area guides, but when I have been to place any of those pictures on my wall so I might respect the fantastic thing about the chook, it will be Dyer’s.


Birds of Belize and Birds of Costa Rica are each spectacular, informative, well-organized area guides, distinguished by the experience, expertise, and abilities of their authors. Birders might have ideas about its use of different taxonomy, however I believe most vacationers shall be blissful to have present guides to those well-liked international locations. There’s a actual want for a brand new information for Belize. H. Lee Jones’ Birds of Belize is an effective area information however organized with plates separate from species accounts, and lots has occurred within the birding world since 2004. The Peterson Subject Information to Birds of Northern Central America by Jesse Fagan and Oliver Komar (2016) does cowl Belize, but in addition Guatemala, Honduras, and El Salvador.

Costa Rica, however, has a wealthy ornithological ebook historical past, together with the basic A Information to the Birds of Costa Rica by F. Gary Stiles and Alexander F. Skutch (1989), an encyclopedic remedy nonetheless price learning. The beneficial area information has lengthy been The Birds of Costa Rica: A Subject Information, 2nd ed. by Richard Garrigues. I had an opportunity to make use of it in 2021 on a quick journey to Costa Rica and came upon that even in lower than ten years, taxonomic adjustments–many official splits and identify adjustments, together with the Motmot group–made a variety of its entries outdated. Nonetheless, the information was nonetheless very useable. It could be that we weren’t completely bereft of an honest chook information to Costa Rica earlier than this area information got here out, and it’s true that we nonetheless lack guides to different Central American international locations, like El Salvador and Guatamala. But it surely’s beautiful to have this lovely information–each lovely guides–obtainable for research, identification, and adoration of those unbelievable birds.
