Bobolinks had the lowest overall predation rate (22%) and among the passerines, American robins
had the highest (50%).
We investigated the mass death of American Robins
(Turdus migratorius) that had congregated around a single fruiting crabapple tree (Malus spp.

Video recording reveals the method of ejection of Brown-Headed Cowbird eggs and no cost in American Robins

The American Robin
followed a night-time pattern similar to that of Hermit Thrushes, but reached the daytime maximum above PZT (98 to 100%) a day ahead of them (Fig.
In addition to the Northern Cardinal and American Goldfinch, other plush Audubon birds that have the highest demand include the Common Loon, Red-winged Blackbird, Baltimore Oriole, Blue Jay, American Robin
, Black-capped Chickadee, Eastern Bluebird and Western Meadowlark.
Frequent timed counts over 2 hrs produced an estimated total of 25,000 birds dominated by American Robins
(Turdus migratorius), Cedar Waxwings (Bombycilla cedrorum), and Yellow-rumped Warblers (Dendroica coronata).
These data suggest that at least two species of birds, the American robin
and the veery, may be reservoirs for A.
Our goal was to clarify the meaning of the American Robin
seet call and conspecifics' responses to the call.
Cardinals have also exhibited intraspecific cooperative breeding behavior among unrelated individuals (Halkin and Linville 1999), as well as an instance of feeding of American Robin

Species with [greater than or equal to] 10 dead individuals (this level appeared to be a natural break in the data) included White-throated Sparrow (Zonotrichia albicollis), Ovenbird (Seiurus aurocapilla), American Robin
(Turdus migratorius), Swainson's Thrush (Catharus ustulatus), Dark-eyed Junco (Junco hyemalis), Ruby-throated Hummingbird (Archilochus colubris), and Northern Cardinal.
Our study aimed to define the competence of the American robin
, Turdus migratorius, as a reservoir host for rodent-infecting Borrelia burgdorferi sensu stricto--not B.
