Male House Sparrows Rise to the Occasion

5-28-13 male House Sparrow  070The House Sparrow’s (also known as English Sparrow) reputation leaves a bit to be desired. It is an introduced species which has thrived in North America to the point where it is considered a nuisance species and an agricultural pest. Its tendency to displace native birds such as Eastern Bluebirds and Tree Swallows from nest boxes does not endear it to many bird lovers. However, one has to acknowledge the fact that male House Sparrows are the exception rather than the rule when it comes to parenting. Males help choose the nest site, build the nest, incubate the eggs, brood and feed the nestlings and keep the nest clean by removing the nestlings’ fecal sacs. That’s more than can be said for some of our most admired species, such as male Ruby-throated Hummingbirds, which disappear shortly after copulation.
