Plant genera (Cornus, Rubus, and Lonicera) used by catbirds at GWEL for nesting match the genera reported elsewhere (Cimprich and Moore 1995).
From late May-July 2007, we located and monitored the nests of seven species known to breed in edge habitat: Tree Swallow (Tachycineta bicolor), Eastern Bluebird (Sialia sialis), Gray Catbird (Dumetella carolinensis), Brown Thrasher (Toxostoma rufum), Yellow Warbler (Dendroica petechia), Northern Cardinal (Cardinalis cardinalis), and Red-winged Blackbird (Yasukawa and Searcy 1995, Imbeau et al.
Alternatively, we find that other common birds, including American robins, gray catbirds, and house sparrows, may play a greater role in supporting enzootic transmission.
These species included American robin, American crow, black-capped chickadee, blue jay, button quail, common grackle, eastern tufted titmouse, gray catbird, house sparrow, mourning dove, northern cardinal, sharp-shinned hawk, wood thrush, domestic cat, domestic cow, domestic dog, horse, sheep, white-footed mouse, and white-tailed deer.

builds a shallow, cup-shaped nest in which two cream-colored eggs are laid and tended.
But as hundreds of twitchers flocked to see the Grey Catbird - the first ever seen in Britain - they were devastated to find it had left again, still aboard the luxury liner as it headed for a two week cruise of the Mediterranean.
I got my bird book out and identified it as the Grey Catbird.
8:45 THE INFLUENCE OF TESTOSTERONE AND MIGRATION ON THE RELAPSE OF PLASMODIUM RELICTUM IN EXPERIMENTALLY INFECTED GRAY CATBIRDS (DUMETELLA CAROLINENSIS)
To investigate the individual and synergistic effects of these variables, I will use the malaria parasite Plasmodium relictum and gray catbirds (Dumetella carolinensis).
Specificity was excellent (98%), except for false-positive results that occurred mostly in Gray Catbirds (Dumatella carolinensis), Green Herons (Butorides virescens), and tests of blood and tissues.
False-positive results in oral VecTests were observed in 36 (2%) of 1,900 RT-PCR-negative birds and rarely occurred in species, with the exception of Gray Catbirds (Dumatella carolinensis) (12%, 13/111) and Green Herons (Butorides virescens) (75%, 6/8) (Table 1).
For example, he found that gray catbirds
exposed to the disease did not infect ticks.
