The Nest and Eggs of the Rufous Mourner (Rhytipterna h. holerythra)
(2017-09-01)
We provide the first description of nest architecture and composition, adult construction behavior, and egg characteristics for the genus Rhytipterna. We provide these data for a nest of the Rufous Mourner (Rhytipterna h. ...
First record of Lesson's Seedeater Sporophila bouvronides in Costa Rica
(2022)
We report the first record of Lesson’s Seedeater Sporophila bouvronides, a South American species, in Costa Rica. It was seen at Tortuguero, in the lowlands of north-east Costa Rica in June 2022. The record is perhaps ...
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, ...
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 ...
Eavesdropping avoidance and sound propagation: the acoustic structure of soft song
(2017-12)
Many species use low-amplitude (soft) song during close range interactions with conspecifics, such as in aggressive encounters or courtship displays. It has been suggested that soft song is adapted to limit eavesdropping ...
The first record of an audible sound produced by a ghost moth, Phassus (Hepialidae) from Costa Rica
(2015)
Sound production in lepidopteran adults has been reported in at least 13 families. The
majority of these families produce ultrasonic sounds that are inaudible to humans. Here we report
the first record of an audible sound ...
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 ...
Relative Importance for Lincoln’s Sparrow (Melospiza lincolnii) Occupancy of Vegetation Type versus Noise Caused by Industrial Development
(2022)
Anthropogenic noise can create an acoustic environment detrimental for animals that communicate using acoustic signals. Currently, most studies of noise and wildlife come from traffic noise in cities. Less is known about ...
Geographic variation in the duets of the Rufous-naped Wren (Campylorhynchus rufinucha) complex
Variación geográfica en los duetos de la Matraca Nuquirrufa (Campylorhynchus rufinucha)
(2020)
Acoustic signals used in animal communication play a key role in mate attraction, species recognition, and territory defense. Variation in acoustic signals may reflect population structure, lack of gene flow, and phylogenetic ...
Sexual size dimorphism and acoustical features of the pre-advertisement and advertisement calls of Rhinophrynus dorsalis Duméril & Bibron, 1841 (Anura: Rhinophrynidae)
(2015)
Las interacciones entre selección natural, selección sexual, y los requerimientos ecológicos específicos de las especies son responsables de la evolución de comportamientos complejos de cortejo y estrategias reproductivas. ...
