Social Organization In A Nesting Population Of Eastern Willets (Catoptrophorus Semipalmatus)
Willet (Catoptrophorus semipalmatus) Science Article 1 abstract The breeding ecology of eastern Willets (Catoptrophorus semipalmatus) was studied over a 3-yr period in a salt marsh on the Atlantic coast of Virginia. During the study,171 adults were color-marked MARSHALL A. HOWE, The Auk 99: 88-102. January 1982 Download article download full text (pdf)
Yellow Warbler nests: building materials and cowbirdparasitism
Yellow Warbler (Dendroica petechia) Science Article 4 abstract Nests are traditionally defined as receptacles in which to house eggs and chicks; however, for the Yellow Warbler (Dendroica petechia), nests may have additional biological significance, especially with respect to Brown-headed Cowbird (Molothrus ater) parasitism.

Notes on the Yellow Warbler in Surinam.
Yellow Warbler (Dendroica petechia) Science Article 9 abstract The Yellow Warbler (Dendroica petechia) is a common winter visitor in Surinam. According to Zimmer (Amer. Mus.Novit. No. 1428, 1949: 5), only the race aestiva has been taken there, but the race brewsteri probably also occurst here since it has been found in both British and French […]
Observations on Migratory Turkey Vultures and Lesser Yellow-headed Vultures in Northern Colombia
Turkey Vulture (Cathartes aura) Science Article 1 abstract Turkey Vultures (Cathartes aura) breed from southern Canada to Tierra del Fuego, while Lesser Yellowheaded Vultures (Cathartes burrovianus) occur from M xico through Central America to northern Argentina and Uruguay (Meyer de Schauensee 1966).It has long been known that Turkey Vultures breeding in the northern parts of […]
Olfactory sensitivity of the Tturkey vulture (Cathartes aura) to three carrion-associated odorants
Turkey Vulture (Cathartes aura) Science Article 2 abstract The Turkey Vulture (Cathartes aura) is generally thought to rely on olfactory cues to locate carrion. Because vertically rising odorants are dispersed rapidly by wind turbulence, we predict that Turkey Vultures should be highly sensitive to these chemicals to detect them at foraging altitudes. STEVEN A. SMITH […]
Pre-Nesting Behavior Of The Swallow-Tailed Kite (Elanoides Forficatus), Including Interference By An Unmated Male With A Breeding Pair
Swallow-tailed Kite (Elanoides forficatus) Science Article 2 abstract Snyder( 1974) has described the breeding biology of the Swallow-tailed Kite (Elanoides forficatus). My observations of their pre-nesting behavior, made while staying at the Archbold Biological Station at Lake Placid, Florida, confirm his on copulations,courtship feeding, and nest-building Lawrence Kilham, Raptor Research 14(1):29-31 Download article download full […]
Food Deliveries At Swallow-Tailed Kite Nests In Southern Florida
Swallow-tailed Kite (Elanoides forficatus) Science Article 3 abstract We studied the diets of nesting Swallowtailed Kites (Elanoides forficatus) at eight nests in 1988
Siblicide In Swallow-Tailed Kites
Swallow-tailed Kite (Elanoides forficatus) Science Article 1 abstract We studied the reproductive behavior of Swallow-tailed Kites (Elanoides forficatus) in northern Guatemala. Modal clutch size was two (range l-2), but no nests succeeded in fledging more than one young. RICHARD I? GERHARDT, Wilson Bull., 109(l), 1997, pp. 112-120 Download article download full text (pdf)
Roosting habits of the Swallow-tailed Kite.
Swallow-tailed Kite (Elanoides forficatus) Science Article 5 abstract Surinam the Swallow-tailed Kite (Elanoides forficatus) is one of the commonest raptors. Present all through the year and sociable at all seasons, it usually occurs in flocks of up to 30 individuals. My records show no evidence that its numbers are augmented at any particular season by […]
