Two Intresting Black Mildews from Kannur, Kerala

Abstract :

Nesting ecology of house sparrow, Passer domesticus, was studied from August 2013 to December 2013 in Punavasipatty and Koothur Villages, Tamil Nadu, India. In total, 111 and 109 nests of house sparrows were located and used for the present study in Punavasipatty and Koothur Villages respectively. Nests were constructed on both plants and man-made substrates using largely small twigs, rootlets, fibers, rugs, etc. Number of eggs laid by house sparrow varied from a minimum of one to a maximum of five eggs. The incubation period varied from seven to 12 days. The nestlings remain in the nest from nine to 14 days. Irrespective of study areas, nests were largely constructed on plants (180) followed by man-made structures (40). Among the man-made structures, majority of the nests were on concrete-roofed houses.
