NESTING BIOLOGY OF THE INDIAN SPARROW (PASSER INDICUS) IN THE FLATLANDS OF TASHKENT REGION
Аннотация
Observations on the nesting biology of the Indian sparrow were conducted in Boka district of Tashkent region. 392 nesting pairs of birds were found in a colony formed on the wall of a ravine on the bank of a waste water canal. All processes in 12 nests were monitored in order to study the nesting biology of the Indian sparrow. Egg-laying of birds in the colony began on May 10 and continued until May 18. A total of 72 eggs were laid in reference nests. Hatching of chicks is completed by the second half of June. Both sexes fed 3, 8, and 10-day-old chicks 148, 183, and 189 times during the day, respectively. The average mass of 11-day-old young birds (n=11) was 22.96 g, with the beak length 6.58 mm, wing length 53.5 mm, tarsus length 19.77 mm and tail length 28.26 mm. It was observed that the chicks left the nest when they are 12-13 days old. By the end of the breeding season, 54 chicks had hatched from the reference nests.
