Third official Audubon Christmas Bird Count: Tikal (GMTK) 2008
organized by CAYAYA BIRDING
Compilers: Knut Eisermann and Claudia Avendaño, CAYAYA BIRDING, January 2009
The third edition of the Christmas Bird Count in the Tikal National Park took place on 19 December 2008. Among the 42 participants were several birdwatching novices, showing that Christmas Bird Counts help the Guatemalan birding community to grow. Some participants were local guides who improved their knowledge on the avifauna in the Mayan World with the help of the more experienced observers.
Weather conditions were favorable. Three species of owls could be recorded in the rainless night. At dawn the rain caused a pretty low activity, but later the weather improved considerably.
A total of 2700 birds of 193 species was recorded (22 species more than in 2007). In addition, 17 species more were recorded during the count week. Each group recorded between 87 and 97 species. Thirteen species were recorded by each of the eight birding groups: Keel-billed Toucan, Black-headed Trogon, Ivory-billed Woodcreeper, Bright-rumped Attila, Brown Jay, Spot-breasted Wren, Wood Thrush, Black-and-White Warbler, Magnolia Warbler, American Redstart, Summer Tanager, Montezuma Oropendula, and Black-cowled Oriole. A total of 75 species was recorded by only one or two of the eight birding groups, indicating a high percentage of "rare" species in the bird community of the Tikal forest. An increasing number of observers during the Christmas Bird Counts will lead to an increased number of detected species. Over 400 bird species have been recorded in the northern Petén.
The most abundant species during this Christmas Bird Count were Montezuma Oropendula (358 birds), Wood Thrush (78), Magnolia Warbler (78), Brown Jay (73), Vaux's Swift (66), Ocellated Turkey (63), Collared Aracari (56), Lesser Greenlet (56), Gray Catbird (52), and Keel-billed Toucan (50).
Noteworthy was a Swallow-tailed Kite seen by the group led by Aquiles Estuardo Hernández, because this species is a summer resident in Tikal and winters in South America. A Philadelphia Vireo was photographed by Chris Moorman on 21 December, documenting a rare record of this species in Tikal. A Black Catbird was seen by Chris Moorman on 22 December in Tikal, and he photographed another one in Uaxactún (outside the count circle) on 23 December. Swainson's Warbler is an uncommon species in the Tikal National Park. One bird was seen during the count, and several more were seen by a research team of North Carolina State University led by John Gerwin and Neil Chartier, studying Swainson's Warblers on their wintering grounds in the eastern Maya Biosphere Reserve.
The Tikal National Park is part of the Maya-Lacandon Important Bird Area (IBA GT001) and this Christmas Bird Count is a simple tool to monitor bird populations in this IBA. A total of 18 species of conservation concern were recorded during the 2008 count, including four Near Threatened species (Great Curassow, Ocellated Turkey, Black Catbird, and Golden-winged Warbler) and 16 species restricted to the Gulf Caribbean Slope.
