Crowing in relation to status in roosters

Article Abstract:

A study has been conducted to examine the relationship between crowing and dominance in domestic roosters, Gallus gallus domesticus. The results revealed that dominant males crowed more often than subordinate males and produced louder crows. However, females were not observed to respond to the crowing of either groups. This suggests that crowing among roosters is a sign of social status, but not sexual dominance.

Communicating about danger: Urgency alarm calling in a bird

Article Abstract:

Vertebrate flee alarm calls can provide information about the predator and some mammalian alarm calls communicate the degree of danger and therefore urgency of escape. It is believed that the individuals respond approximately to calls in the absence of any other cues and that the avian flee alarm calls can convey urgency.

Begging to differ: scrubwren nestlings beg to alarm calls and vocalize when parents are absent

Article Abstract:

An experiment is conducted to check if nestling scrubwrens, Sericornis frontalis, increase begging intensity with hunger but reduce it after adult alarm calls. It is suggested that nestlings acquire the ability to respond appropriately to alarm calls late in the nestling period.
