It was positively related to occupancy in Northern cardinal and American robin (Turdus migratorius) and negatively related to gray catbird
(Dutnetella carolinensis) occupancy.
It's been a long time since a new British bird was found in North Wales, the last being a Gray Catbird
at RSPB South Stack in October 2001.
I spent years imagining a flying cat, until I finally saw a picture of a gray catbird
All other hosts with >10 individuals tested, including opossums, gray and red squirrels, and all 4 species of birds tested (veery [Catharus fuscescens], gray catbird
[Dumetella carolinensis], wood thrush [Hylocichia mustelina], and American robin), had mean levels of reservoir competence <6%.
In the gray catbird
study: "80 percent of the birds killed were done in by predators, of whom cats represented 47 percent.
For example, squirrels and birds, such as the robin, Northern bobwhite quail, gray catbird
, Eastern kingbird and the great crested flycatcher, savor the ripe berries in autumn.
The call of the gray catbird
in America sounds like a mewing eat, while the unrelated catbirds in Australia sound like alley eats in heat.
The Gray Catbird
, a native of north America and a member of the thrush family, was last sighted off Jersey in the early 1970s.
Because cattle eat new growth, there is little or no regeneration of the trees that form the forest canopy and subcanopy, where many migrants forage; most of the understory vegetation, used by species like the gray catbird
and Canada warbler, has been lost; and grass has replaced leaf litter, where various thrushes and the ovenbird like to rummage.
to chronicle breeding behavior, searching for evidence of birds staking out and defending their territory, I became fascinated by the song of the Gray Catbird
, a common breeder in that area.
To evaluate potential differences in fitness relative to phenological period, we estimated mass change in 13 species of landbird migrants [Red-eyed Vireo (Vireo olivaceus), Ruby-crowned Kinglet (Regulus calendula), Hermit Thrush (Catharus guttatus), Veery (Catharus fuscescens), Wood Thrush (Hylocichla mustelina), Gray Catbird
(Dumetella carolinensis), Blue-winged Warbler (Vermivora pinus), Nashville Warbler (Vermivara mficapilla), Magnolia Warbler (Setophaga magnolia), Chestnut-sided Warbler (Setophaga pensylvanica), Ovenbird (Seiurus aurocapillus), Common Yellowthroat (Geothlypis trichas), and White-throated Sparrow (Zonotrichia albicollis) ].
For instance, most nests found on the State Game Lands (SGL) 33 ROW in 1991-92 were those of early successional species, including field sparrow (Spizella pusilla), gray catbird
(Dumetella carolinensis), eastern towhee (Pipilo erythrophthalmus), common yellowthroat (Geothlypis trichas), and indigo bunting (Passerina cyanea) (Bramble et al.
