Sparrows From Different Worlds

Image
I photographed these 2 commonly-seen sparrows about 13 minutes apart, but their lineages are "worlds" apart. The 1st is a House Sparrow , more commonly seen near human dwellings. They are Old World sparrows , and perhaps because they evolved longer around humans, they're fairly tolerant of humans.  And the 2nd is (another) Song Sparrow , which is a New World sparrow that seems willing to sing for us but generally won't nest especially close to us. Although we have a lot of Old World sparrows here in the US, almost all of them are House Sparrows, and here in NJ you're unlikely to find any other Old World sparrows. As you might suspect, all the Old World sparrows and all the New World sparrows are more closely related to the other sparrows of their "world" than they are to sparrows of the other "world".  And while Song Sparrows are considered skilled and prolific singers, the House Sparrow vocalization mostly sounds like they're calling you ...

House Sparrow

While yesterday's Mourning Dove are rare beneficiaries of the bird food I've left out for the Dark-eyed Juncos , much more frequent beneficiaries are the House Sparrows . As one of the most successful invasive bird species in North America (the European Starling is the other one), House Sparrows are less popular with birders, naturalists, and ecologists than almost any bird we see. This actually extends to the law; while harming most birds is illegal (with some regulated exceptions for game birds), these guys aren't protected by federal law. (Local animal cruelty laws could still apply though.) These guys are Old World sparrows , and are thus not particularly closely related to virtually all the other sparrows you see; almost all the other sparrows you see are New World sparrows . (New World sparrows are actually more closely related to Old World Buntings than Old World Sparrows. Such is the confusing world of taxonomy.) March 2021 at Finderne
