Abstract
The research was carried out in October-March 2009—2013 at Zvenigorod Biological Station (the Moscow Region, Russia, 55°44ґ N, 36°51ґ E). Birds were captured by mist-nets. Standard metabolic rate and respiratory quotient were measured by flow-through respirometry in 64 experiments on Coal Tits. Standard metabolic rate and respiratory quotient had well pronounced diurnal rhythms with minimum in the nighttime (from 2 a.m. to 5 a.m.) and maximum in the daytime (from 11 a.m. to 2 p.m.). A significant relationship between the standard metabolic rate and the respiratory quotient was found. The maximum difference between standard metabolic rates during daytime and nighttime was 55%. During the night, mainly fat reserves were oxidized, whereas proteins were oxidized during the daytime.
