COOPERATIVE DISPLAY AND LEKKING BEHAVIOR OF THE LANCE-TAILED MANAKIN (CHIROXIPHIA LANCEOLATA)

TLDR
The Lance-tailed Manakin display repertoire provides information useful in comparative analyses of the origin and evolution of display behavior within the manakin clade and in studies of the adaptive consequences of individual behavior within this species.

Diet of Ornate Hawk-Eagle (Spizaetus ornatus)

TLDR
A pair and one young individual of this species registered in the southeast of Minas Gerais state, eastern portion of the Espinhaço Range, Brazil, and a literature review on the diet of the species was carried out to gather data on food habits.

LIFE HISTORIES OF CENTRAL AMERICAN PIGEONS

TLDR
The biology of the Central American representatives of the Columbidae is outlined, species by species, and such generalizations as seem to be warranted by the available information are drawn.

A STUDY OF THE RUFOUS-FRONTED THORNBIRD

TROUPIAL The melodious Troupial (Icterus icterus), or turpial as it is called in its native land, the national bird of Venezuela, is a large oriole about 10 inches long. Its head, throat, chest,

Possible scavenging behavior in Ornate Hawk-Eagle (Spizaetus ornatus) in Amazonas, Brazil

We provide documentation of the first observations of interactions with carrion in the Ornate Hawk-Eagle (Spizaetus ornatus), a species formerly assumed only to prey on live food items. During

Complementary Diet of Cathartes burrovianus (Cathartidae) With Fruit Elaeis guineensis (Arecaceae)

TLDR
It was concluded that C. burrovianus feeds on the fruits of the palm E. guineensis not only as an alternative food in the absence of carcasses, but also a complement to their dietary needs, the first record of this feeding behavior.

Cooperative Hunting and its Relationship to Foraging Success and Prey Size in an Avian Predator

TLDR
Pairs of Aplomado falcons consistently showed signs of cooperative behavior such as use of a simple coordinative signal, and some division of labor between participating individuals, but there was no evidence that cooperative hunting increased the range of feasible prey sizes.

Phylogenetic Analysis of the Evolution of Display Behavior in the Neotropical Manakins (Aves: Pipridae)

TLDR
Phylogenetic systematic methods were applied in an investigation of the evolution of lek display behavior in the Neotropical manakins (Aves: Pipridae), resulting in three phylogenetic analyses of 44 display characters.

THE RELATIONSHIP BETWEEN CLIMATE AND ANNUAL CYCLES IN THE COTINGIDAE

  • D. Snow
  • Environmental Science, Biology
  • 2008
TLDR
It seems that both breeding and moult are as far as possible timed to coincide with this most favourable period; but whereas the moult takes a more or less fixed length of time the period when breeding is possible varies greatly in different species.
