December 2, 2016 - Vesper Sparrow (Pooecetes gramineus)
Requested by: rainhawk
These sparrows are found across North America, wintering in Mexico and the southern United States and breeding in Canada and the northern United States. They feed primarily on grains and the seeds of grasses and weeds, along with insects during the breeding season. Their large range is due to their adaptability and they are often among the first birds to return to abandoned mining areas and farms. Analyses of their songs suggest that young sparrows learn to sing from older birds, as the songs of neighboring sparrows are more similar than those living far away. Their nests are shallow cups built from woven grasses on the ground. Females incubate the eggs and both parents care for the chicks.
