Quantifying difference in vocalizations of bird populations
Populations of a bird species can evolve over time to become a new species. While plumage patterns and other morphological information can remain constant, the vocalizations of a given population may have diversified enough to warrant reclassification. Thus ornithologists are interested in how to measure call and song similarity in birds in a systematic, repeatable manner. Given the success of ...

متن کاملParasitized and non-parasitized prey selectivity by an insectivorous bird
The identification and conservation of naturally occurring enemies of crop pests is an important means of improving biological control in cropping systems. One particularly important potential mechanism whereby birds might stabilize and improve pest control is consumption of individual prey that escape mortality from other agents of biological control. We tested the hypothesis that birds prefer...
متن کاملThe Costs of Bird Strikes and Bird Strike Prevention
Collisions between birds (and other wildlife) and aircraft are known to cause substantial losses to the aviation industry in terms of damage and delays every year. Techniques exist to control bird numbers on airfields and hence to reduce the number of wildlife strikes, but they are applied at widely different levels from airport to airport. Some of this variation may be due to differing levels ...
متن کاملPrevalence of Avian Influenza in Live Bird Markets, Bird Gardens, and Zoos in Iran in 2015: A Cross-sectional Study
Avian Influenza (AI) H9N2 is endemic in Iran; therefore, it is necessary to estimate the disease prevalence among birds in live bird markets (LBMs) and assess the risk spread across the country. Accordingly, this study aimed to estimate the prevalence of AI subtypes in LBMs, bird gardens, and zoos during October and November 2015 in Iran and investigate the associated risk factors. Data related...
