Acoustic localization of antbirds in a Mexican rainforest using a wireless sensor network
Collier, T. C.; Kirschel, A. N. G.; Taylor, C. E. (2010)Acoustic localization is a promising method to passively observe vocal animal species, but remains difficult and time consuming to employ. To reduce the labor intensity and impact of deployment, an acoustic localization ...

Acoustic monitoring in terrestrial environments using microphone arrays: Applications, technological considerations and prospectus
Blumstein, Daniel T.; Mennill, D. J.; Clemins, P.; Girod, L.; Yao, K.; Patricelli, G.; Deppe, J. L.; Krakauer, A. H.; Clark, C.; Cortopassi, K. A.; Hanser, S. F.; Mccowan, B.; Ali, Andreas M.; Kirschel, A. N. G. (2011)1. Animals produce sounds for diverse biological functions such as defending territories, attracting mates, deterring predators, navigation, finding food and maintaining contact with members of their social group. Biologists ...

Automated species recognition of antbirds in a Mexican rainforest using hidden Markov models
Trifa, V. M.; Kirschel, A. N. G.; Taylor, C. E.; Vallejo, E. E. (2008)Behavioral and ecological studies would benefit from the ability to automatically identify species from acoustic recordings. The work presented in this article explores the ability of hidden Markov models to distinguish ...

Birdsong tuned to the environment: Green hylia song varies with elevation, tree cover, and noise
Kirschel, A. N. G.; Blumstein, Daniel T.; Cohen, R. E.; Buermann, W.; Smith, T. B.; Slabbekoorn, H. (2009)Animals that communicate acoustically must compete for acoustic space in order to convey their signals effectively. Tropical rainforest birds live in an extremely diverse acoustic community consisting of other birds, ...

Character displacement of song and morphology in African tinkerbirds
Kirschel, A. N. G.; Blumstein, Daniel T.; Smith, T. B. (2009)Divergence in acoustic signals between populations of animals can lead to species recognition failure, reproductive isolation, and speciation. Character displacement may facilitate coexistence of species in natural ...

Current and future suitability of wintering grounds for a long-distance migratory raptor
Kassara, Christina; Gangoso, L.; Mellone, U.; Piasevoli, G.; Hadjikyriakou, T. G.; Tsiopelas, N.; Giokas, Sinos; López-López, P.; Urios, V.; Figuerola, J.; Silva, R.; Bouten, W.; Kirschel, A. N. G.; Virani, M. Z.; Fiedler, W.; Berthold, P.; Gschweng, M. (2017)Conservation of migratory species faces the challenge of understanding the ecological requirements of individuals living in two geographically separated regions. In some cases, the entire population of widely distributed ...

The evolutionary consequences of interspecific aggression
Grether, G. F.; Anderson, Christopher N.; Drury, J. P.; Kirschel, A. N. G.; Losin, N.; Okamoto, K.; Peiman, K. S. (2013)Competition has always been a cornerstone of evolutionary biology, and aggression is the predominant form of direct competition in animals, but the evolutionary effects of aggression between species are curiously understudied. ...

Novel courtship behavior in the Little Greenbul (Andropadus virens)
Kirschel, A. N. G. (2008)The Little Greenbul (Andropadus virens) is a common African forest bird that is thought to form monogamous pair bonds. In March 2007, I observed a male hanging below a presumed female perched on a branch, apparently ...

Predicting bird song from space
Smith, T. B.; Harrigan, R. J.; Kirschel, A. N. G.; Buermann, W.; Saatchi, S.; Blumstein, Daniel T.; de Kort, S. R.; Slabbekoorn, H. (2013)Environmentally imposed selection pressures are well known to shape animal signals. Changes in these signals can result in recognition mismatches between individuals living in different habitats, leading to reproductive ...

Smithornis broadbills produce loud wing song by aeroelastic flutter of medial primary wing feathers
Clark, C. J.; Kirschel, A. N. G.; Hadjioannou, L.; Prum, R. O. (2016)Broadbills in the genus Smithornis produce a loud brreeeeet during a distinctive flight display. It has been posited that this klaxon-like sound is generated non-vocally with the outer wing feathers (P9, P10), but no ...

Territorial dynamics of Mexican Ant-thrushes Formicarius moniliger revealed by individual recognition of their songs
Kirschel, A. N. G.; Cody, M. L.; Harlow, Z. T.; Promponas, Vasilis J.; Vallejo, E. E.; Taylor, C. E. (2011)The ability to monitor interactions between individuals over time can provide us with information on life histories, mating systems, behavioural interactions between individuals and ecological interactions with the ...

Testing alternative hypotheses for evolutionary diversification in an african songbird: Rainforest refugia versus ecological gradients
Kirschel, A. N. G.; Slabbekoorn, H.; Blumstein, Daniel T.; Cohen, R. E.; de Kort, S. R.; Buermann, W.; Smith, T. B. (2011)Geographic isolation in rainforest refugia and local adaptation to ecological gradients may both be important drivers of evolutionary diversification. However, their relative importance and the underlying mechanisms of ...

Using songs to identify individual mexican antthrush formicarius moniliger: Comparison of four classification methods
Kirschel, A. N. G.; Earl, D. A.; Yao, Y.; Escobar, I. A.; Vilches, E.; Vallejo, E. E.; Taylor, C. E. (2009)This study compares the ability of four classification methods to distinguish between songs of individual Mexican Antthrush Formicarius moniliger: self-organizing maps (SOMs), discriminant function analysis, fuzzy logic ...
