Corvids show an episodic memory with the temporal information on 'when' an event has actually occurred. We propose that crows keep the time and duration of an event by involving the endogenous circadian clocks, reliably measured in behavioural rhythms. The aim of the present study is to find out if circadian rhythms were involved in the organization of daily behavioural patterns in Indian house crows, Corvus splendens. We monitored the activity, ingestive (feeding: eating and drinking) and grooming (preening) behaviours in crows sequentially exposed to 12 h light : 12 h darkness (12 L : 12 D) and dim constant light (LLdim) for one and three weeks respectively. The behavioural patterns were synchronized and diurnal was under 12 L : 12 D, while freeran had a circadian period under the LLdim. In general, eating and drinking, not grooming, patterns were more closely related to the activity - rest cycle. These results show the persistence of circadian rhythms in behavioural patterns, and extend the idea that endogenous circadian clocks determine daily timing of the physiology and behaviour in Indian house crows, in particular, and birds, in general.Keywords

This study investigated whether short-term protein supplement to the seed-only diet during adulthood would impact the production and song features in male zebra finches (Taeniopygia guttata). In singly housed adult male zebra finches provided daily with seeds as food without or with 1 g of egg white protein supplement (equivalent to ~0.11 g egg proteins) under 12 h light : 12 h dark condition for 8 weeks, we recorded singing pattern at the beginning and end over 2 days when a female conspecific shared his cage. We found no effect of the egg protein supplement on daily song production, song bout duration and motifs per bout as well as the spectral features of the song, viz. motif duration, amplitude, pitch, goodness, mean frequency, frequency modulation, amplitude modulation or entropy. Perhaps, as sexually selected trait, song quality is not directly related to body metabolism. It is likely that seeds provided met energy requirement for vocalization (song production), and so additional egg white protein supplement did not affect the singing behaviour in adult zebra finches.Keywords
