Abstract Many species of trogons (Trogoniformes: Trogonidae) gather in mixed-gender calling assemblages during the breeding season. These assemblages have been compared to leks and are usually assumed to function in mate choice; however, no field data exist to support this hypothesis. I present five non-mutually exclusive hypotheses for the function of mixed-gender calling assemblages and test the predictions using field data from Black-headed Trogons (Trogon melanocephalus) in a lowland dry… Expand
Sympatric black-headed and elegant trogons focus on different plumage characteristics for species recognition
TLDR
This study provides the first experimental evidence that specific plumage patches are used for species recognition and that closely related species may use different traits for species Recognition. Expand

Breeding Behavior of Elegant Trogons in Southeastern Arizona
TLDR
Elegant Trogons nesting in Arizona have different behaviors from other Neotropical members of the Trogonidae, especially with regards to their durations of incubation and feeding, and they feed nestlings insects rather than fruit. Expand
Prospecting for nest sites by cavity-nesting ducks of the genus Bucephala
TLDR
The pattern of post-laying visitation of nest sites by non-nesting females in three species of cavity-nests ducks, the Common and Barrow's goldeneyes (Bucephala clangula and B. islandica) and the Bufflehead and it is proposed that these females were "prospecting" for nest sites in preparation for the next breeding season.

Mutual interference during nest-prospecting in the shelduck, Tadorna tadorna
TLDR
The individual survival value of joining groups may be to reduce the risk of predation on the adults, but is perhaps more likely to be to gain information on the location of good nest sites. Expand
Ecological Characterization of a Costa Rican Dry Forest Caterpillar Fauna
TLDR
The dry forests of Costa Rica's Santa Rosa National Park range from deciduous and 2 m tall to nearly evergreen and 30 m tall, and this vegetation and a complex mosaic of secondary succession in old fields and pastures supports at least 3 140 species of caterpillars. Expand
Prospecting in the collared flycatcher: gathering public information for future breeding habitat selection?
Abstract Visiting breeding patches can allow prospecting individuals to gather information on local patch quality to make optimal decisions about selecting a breeding habitat in the following year.Expand
Non–territorial nightingales prospect territories during the dawn chorus
TLDR
It is suggested that non–territorial male nightingales use the dawn chorus to assess singing residents or territory occupancy and may thus play a role in territory maintenance. Expand
Timing of prospecting and the value of information in a colonial breeding bird
TLDR
It was found that the bulk of prospecting occurred when the best information on local reproductive success was available, consistent with the potential use of conspecific reproductive success as a proximate cue for habitat selection. Expand
Extra pair paternity in birds: a review of interspecific variation and adaptive function
TLDR
The remaining challenges of understanding the relative roles of genes and ecology in determining variation between taxa in the rate of extra paternity are highlighted, and testing for differences between extra‐pair offspring and those sired within‐pair is highlighted. Expand

TLDR
The results provide the first experimental evidence, to the authors' knowledge, of the links between information gathering behaviour and breeding habitat selection strategies based on public information. Expand
