Birding 8-03 Pages 356-403 The Secret of the Predator’s Eyes. Steiner-Germany has developed the new Peregrine binocular, a new record in light transmission that al- lows faster discovery and location of birds hidden in foliage or shadows. Since birds are often visible for only a few seconds, seeing their true colors in bright contrast and clearly identifying the most subtle color differences is extremely important. With Steiner’s new Peregrine, a new level of brightness and natural color balance is achieved by use of a new dielectric prism coating, by which over 40 layers of titanium oxide and other rare minerals are alternately applied to the glass surfaces. This Broad-Band Coating (BBC) results in superior light transmission performance over a broad range of colors. The Peregrine is also phase corrected for sharpest possible, distortion free images and the optical glass is manufactured at our new state-of- the-art roof prism glass production facility in Bayreuth, Germany. The Peregrine falcon is a fast and skillful hunter, in fields and even under trees, aided by the sharpest eyes. The Steiner Peregrine is available in 8x42 and 10x42 models and will maintain its peak performance at any temperature and under any conditions. The Peregrine’s dark-green, light absorbing armored body blends in with natural surroundings, providing an advantage when glassing for easily spooked species.

    his is the 20th published report of the ABA Checklist Committee (hereafter, TCLC), covering the period July 2008– July 2009. There were no changes to commit - tee membership since our previous report (Pranty et al. 2008). Kevin Zimmer has been elected to serve his second term (to expire at the end of 2012), and Bill Pranty has been reelected to serve as Chair for a fourth year. During the preceding 13 months, the CLC final - ized votes on five species. Four species were accepted and added to the ABA Checklist , while one species was removed. The number of accepted species on the ABA Checklist is increased to 960. In January 2009, the seventh edition of the ABA Checklist (Pranty et al. 2009) was published. Each species is numbered from 1 (Black-bellied Whistling-Duck) to 957 (Eurasian Tree Sparrow); ancillary numbers will be inserted for all new species, and these numbers will be included in our annual reports. Production of the seventh edi - tion of the ABA Checklist occupied much of Pranty’s and Dunn’s time during the period, and this com - mitment helps to explain the relative paucity of votes during 2008–2009 compared to our other recent an - nual reports.

  • The Diets of Neotropical Trogons, Motmots, Barbets and Toucans
    The Condor 95:178-192 0 The Cooper Ornithological Society 1993 THE DIETS OF NEOTROPICAL TROGONS, MOTMOTS, BARBETS AND TOUCANS J. V. REMSEN, JR., MARY ANN HYDE~ AND ANGELA CHAPMAN Museum of Natural Scienceand Department of Zoology and Physiology, Louisiana State University,Baton Rouge, LA. 70803 Abstract. Although membership in broad diet categoriesis a standardfeature of community analysesof Neotropical birds, the bases for assignmentsto diet categoriesare usually not stated, or they are derived from anecdotal information or bill shape. We used notations of stomachcontents on museum specimenlabels to assessmembership in broad diet categories (“fruit only,” “ arthropods only,” and “fruit and arthropods”) for speciesof four families of birds in the Neotropics usually consideredto have a mixed diet of fruit and animal matter: trogons (Trogonidae), motmots (Momotidae), New World barbets (Capitonidae), and tou- cans (Ramphastidae). An assessmentof the accuracyof label data by direct comparison to independentmicroscopic analysis of actual stomachcontents of the same specimensshowed that label notations were remarkably accurate.The specimen label data for 246 individuals of 17 speciesof Trogonidae showed that quetzals (Pharomachrus)differ significantly from other trogons (Trogon) in being more fiugivorous. Significant differences in degree of fru- givory were found among various Trogonspecies. Within the Trogonidae, degreeof frugivory is strongly correlated with body size, the larger speciesbeing more frugivorous. The more frugivorous quetzals (Pharomachrus)have relatively flatter bills than other trogons, in ac- cordancewith predictions concerningmorphology of frugivores;otherwise, bill morphology correlated poorly with degree of fiugivory. An analysis of label data from 124 individuals of six speciesof motmots showed that one species(Electron platyrhynchum)is highly in- sectivorous,differing significantlyfrom two others that are more frugivorous(Baryphthengus martii and Momotus momota).

  • Life History of the Black-Throated Trogon
    LIFE HISTORY OF THE BLACK-THROATED TROGON BY ALEXANDER F. SKUTCH N Barro Colorado Island in Gatlin Lake, in the middle of the Isthmus of 0 Panama, I found my first twTo nests of the Black-throated Trogon (Trogon rufus) , in 1935. Both were destroyed by predators before the eggs hatched. Four years later, in the Valley of El General in southern Costa Rica, I found my third nest, which met a similar fate. In most of the succeeding years I have studied birds in the same region, where these trogons are not uncommon, and I have encountered five additional nests. With the exception of one which I did not see until the young were almost feathered, only the last was successful. This was situated on our farm in El General in April, 1958, and enabled me to round out a study begun 23 years earlier. The present paper is, then, a report of observations gathered over nearly a quarter of a century. The slowness of their accumulation is to be attributed to the diffi- culty of finding the nests of the majority of the birds that dwell in tropical rain-forest, and the discouragingly small proportion of these nests that yield living young. APPEARANCE AND RANGE One of the smaller members of its family, the Black-throated Trogon has a total length of about nine inches, of which well over half is accounted for by its long tail. The males’ predominant color is bright metallic green, which covers all the upper surface of head and body and likewise the chest.

  • Habitat Use of Wintering Bird Communities in Sonora, Mexico: the Importance of Riparian Habitats
    Studies in Avian Biology No. 37:53–68 HABITAT USE OF WINTERING BIRD COMMUNITIES IN SONORA, MEXICO: THE IMPORTANCE OF RIPARIAN HABITATS JOSÉ FERNANDO VILLASEÑOR-GÓMEZ Abstract. Riparian systems are dynamic and diverse despite their limited areal extent. They are espe- cially important for breeding bird communities in southwestern US and are highly used as migra- tory corridors; however, their importance for wintering birds has not been assessed systematically. Information from 1,816 standard 10-min point counts was gathered at 85 locations in the State of Sonora, Mexico from sea level to 2,175 m during January and February 2004–2006. I detected 253 bird species across 14 vegetation types, including nine categories of riparian vegetation. Eighty percent of total species were detected in riparian habitats, and 72% were detected in non-riparian habitats. The mean number of species and individuals detected per count were signifi cantly higher in ripar- ian habitats than in non-riparian habitats for migratory species, but not for residents. A hierarchical classifi cation analysis showed that riparian bird communities are different from those in non-riparian communities, and they contribute 22% of the species that comprise the regional avifauna, which is more than any other habitat type. Key Words: habitat use, Mexico, neotropical migrant birds, riparian, Sonora, wintering. USO DE HABITAT DE COMUNIDADES DE AVES INVERNANTES EN SONORA, MEXICO: IMPORTANCIA DE LOS HABITATS RIPARIOS Resumen. Los sistemas riparios son dinámicos y diversos a pesar de su limitada cobertura espacial. Son especialmente importantes para las comunidades de aves que se reproducen en el Suroeste de los Estados Unidos y son usados extensamente como corredores migratorios; sin embargo, su importancia para las aves invernantes no se ha determinado de forma sistemática.
