Physiological constraints related to atmospheric temperature pose a limit to body and appendage
size in endothermic animals. This relationship has been summarised by two classical …

Effective communication in birds is often hampered by background noise, with much research
focusing on the effect of anthropogenic noise on passerine bird song. Continuous low-…

Mediterranean islands provide shelter and sustenance for millions of migrating birds each
year. Humans have historically exploited bird migration through hunting. In Cyprus, trapping …

Many island endemics around the world have evolved from populations of colonists. Further
colonizations may lead to interactions between older and newer colonists. Little is known, …

Bird song mediates speciation but little is known about its genetic basis because of the
confounding effect of vocal learning in model systems. Rhythm, in particular, transcends acoustic …

The regeneration of many climax species in tropical forest critically depends on adequate
seed dispersal and seedling establishment. Here, we report the decreased abundance and …

. Red-fronted Tinkerbird Pogoniulus pusillus (Dumont, 1816) presently comprises three
recognised subspecies, of which two are found in East Africa and one occurs disjunctly in …

Effective communication in birds is often hampered by background noise, with many recent
studies focusing on the effect of anthropogenic noise on passerine bird song. Continuous low…

The distribution of the nominate subspecies of Yellow-fronted Tinkerbird Pogoniulus chrysoconus
has long been thought to extend throughout Uganda south into northwestern Tanzania…

The enormous biological diversity found on Earth, with its variable patterns of colours, sounds
and shapes has long sparked the intellectual curiosity of the scientific community. This …
