An approximately 1-year-old, 40-g captive male northern cardinal (

Here we investigate the activity of the immune system in male and female Northern Cardinals (
Cardinalis cardinalis), a strongly bi-parental species, and the influences of hormones on immune actions during breeding.
Monitoring exposure of northern cardinals,
Cardinalis cardinalis, to cholinesterase-inhibiting pesticides: Enzyme activity, reactivations, and indicators of environmental stress.
Northern 'Cardinal (
Cardinalis cardinalis): Common in winter, males are bright scarlet in color.
These findings are similar to previous results for VecTest, which also tested well with House Finches (Carpodacus mexicanus), Northern Cardinals (
Cardinalis cardinalis), and American Kestrels (Falco sparverius) (4).
The feeding habits and preferences of four species of songbirds, northern cardinals (
Cardinalis cardinalis), song sparrows (Melospiza melodia), dark-eyed juncos (Junco hyemalis), and white-throated sparrows (Zonotrichia albicollis) were examined from November to February of 1980-81, 1981-82, and 1982-83.
The following nine species were present in the unburned site, yet were absent in the burned site: Black-and-white Warbler, Eastern Phoebe, Hairy Woodpecker, Northern Flicker, Ruby-throated Hummingbird, Eastern Towhee, Northern Cardinal (
Cardinalis cardinalis), Cedar Waxwing (Bombycilla cedroruta), and Veery (Catharus fuscescens).
The species infected were a great blue heron (Ardea herodias), 2 American crows (Corvus brachyrhyncos), 2 American robins (Turdus migratorius), 2 mourning doves (Zenaida macroura), a red-tailed hawk (Buteo jamaicensis), a blue-gray gnatcatcher (Polioptila caerulea), a northern mockingbird (Mimus polyglottos), a house finch (Carpodacus mexicanus), and a northern cardinal (
Cardinalis cardinalis).
Oral VecTest performed well for small samples of American Kestrels (Falco sparverius), Northern Cardinals (
Cardinalis cardinalis), Common Grackles (Quiscalus quiscula), and House Finches (Carpodacus mexicanus).
The dilepidid tapeworm, Anonchotaenia rostellata (Rodgers 1941) was described from 13 specimens taken from the small intestine of a northern cardinal,
Cardinalis cardinalis (Linnaeus) collected at Stillwater, Payne County, Oklahoma, in the spring of 1940 (Rodgers 1941).
We placed several feathers from arboreal-nesting bird species [carolina wren (Thryothorus ludovicianus), northern cardinal (
Cardinalis cardinalis), and house sparrow (Passer domesticus)] in the nest cavity.
