This is the finest identification guide to pelagic birds published to date. For the first time, everything you need to prepare for tubenose ID on both east and west coast pelagic trips is accessible in one volume. It's also an authoritative and well-written text on tubenose biology. The book is extremely well-organized to help the user zero in on critical marks. Thus, for example, the section on Pacific gadfly petrels is introduced by five pages of photos and accompanying text showing and comparing the 10 species most likely to be encountered. Following are subsections on each species with comparative photos, including species not yet recorded but which may occur. For Cook's Petrel, there five pages of photos, with comparative shots of De Filippi's Petrel, Black-winged Petrel, and Pycroft's Petrel. Without question, a 2012 WorldTwitch Best Bird Book award winner. In case you missed it, the report of the Jamaica Petrel Pelagic Expedition (November-December 2009) by Hadoram Shirihai, Maria San Román, Vincent Bretagnolle and David Wege is posted on the BirdLife website (pdf). Here's another great article for pelagic birders: First observations at sea of Vanuatu Petrel Pterodroma (cervivcalis) occulta by Hadoram Shirihai & Vincent Bretagnolle, Bull.B.O.C. 2010 130(2):132-140 (pdf).
Until reading the illustrated addedum on accidentals, I hadn't realized that the type specimen of Worthen's Sparrow was collected at Silver City, New Mexico in 1884, from a population subsequently extirpated. In view of this bird's occurrence with Mexican Prairie Dogs at the "Tanque de emergencía" stakeout in Coahuila, Mexico, I wonder if poisoning of prairie dogs may have contributed to its disappearance from the U.S. and most of its Mexican range.
Scroll down on this Surfbirds page to see a fine photo of a mist-netted Gray-breasted Crake Laterallus exilis from Veracruz, Mexico taken by Manuel Grosselet. This small rail can be heard in many places throughout the Neotropical lowlands, including around oxbow lakes in Amazonia. It readily approaches in response to playback but usually is impossible to see in its dense marsh habitat. Coming Soon - New Editions:
