Nest Usurping Occurrence Of The Piratic Flycatcher (Legatus Leucophaius) In Southwestern Costa Rica
(2009)
El Mosquerito Pirata (Legatus leucophaius) roba nidos colgantes o en forma de domo hechos principalmente por tiranidos o icteridos, sin embargo la frecuencia con la cual este mosquero se roba los nidos de otras especies ...
Relationship between species richness of excavator birds and cavity–adopters in seven tropical forests in costa rica
(2009)
The abundance of wood cavities is thought to be a limiting factor for bird species that depend on these cavities for nesting. Thus, it is expected that number of cavity adopters correlates with number of cavity excavators ...
Human waste used as nesting material affects nest cooling in the clay-colored thrush
(2021-09-01)
The internal temperature of nests largely depends on the materials used in their construction because the characteristics of each material affect the isolation of nest walls. In urban environments, the availability of
natural ...
Conceptual and statistical problems with the use of the Shannon-Weiner entropy index in bioacoustic analyses
(2018-04-03)
Information theory and its indices were developed for human communication to predict the amount of information transferred in a message. One such index, the Shannon-Weiner index (SWI), has often been used to analyse ...
House Wrens Troglodytes aedon reduce repertoire size and change song element frequencies in response to anthropogenic noise
(2020-06-09)
Anthropogenic noise (≤ 3 kHz) can affect key features of birds’ acoustic communication via two different processes: (1) song-learning, because songbirds need to hear themselves and other birds to crystallize their song, ...
Urban noise influences vocalization structure in the House Wren Troglodytes aedon
(2013)
Urban habitats are noisy and constrain acoustic communication in birds. We analysed the effect of anthropogenic noise on the vocalization characteristics of House Wrens Troglodytes aedon at two sites with different noise ...
Characteristics of male Spot-bellied Bobwhite (Colinus leucopogon) song during territory establishment
(2012)
In song-learning birds, male song shows a large inter-individual variation that frequently plays an important role in intra- and inter-sexual selection. In other bird groups, such as Galliformes, song learning is absent, ...
Asociación entre la morfología alar y el uso del hábitat en seis especies de palomas (Columbidae) neotropicales
Relationship between wing morphology and habitat use in six species of Neotropical doves (Columbidae).
(2019)
Biomechanics, behavior, and natural history influence wing dimension and shape. Wing design often correlates with features of the habitat in which each species is found. Doves and pigeons (Columbidae family) range from ...
The forgotten habitats in conservation: early successional vegetation
(2019)
Conservation efforts in terrestrial environments have focused on preserving patches of natural
habitats and restoring disturbed habitats, with the main goal of transforming them into forests or habitats that resemble the ...
