First I have to say that I am very fond of Lark Sparrows, I love the harlequin pattern on their face but I also love hearing their songs whether I see them or not. So I thought I would share a few Lark Sparrow facts, a sound recording and of course an image of a Lark Sparrow on the ground.
When I am on Antelope Island this time of the year I hear their calls and songs all over the island but mostly where there is sagebrush and rabbitbrush.
Larks Sparrows are the only members of the genus Chondestes.
Currently their breeding range is shrinking but that is because of reforestation and urbanization in the east. Their historical range expanded because because lands were cleared for agriculture and Lark Sparrows prefer open habitat like grasslands, fields, pastures farmlands and roadsides.
Lark Sparrows often take over old Sage Thrasher or Northern Mockingbird nests instead of building their own. That may or may not be a way of saving energy during the breeding season, I am not sure. There have been reports though of finding Lark Sparrow eggs mixed in with thrasher and mockingbird eggs in nests which suggests that they share their nest with another species.
Lark Sparrows walk on the ground instead of hopping like other passerines and the only time they do hop on the ground is during courtship. The males even strut like turkeys during courtship. Another courting behavior that is unique to Lark Sparrows is that the male will pass a small twig to the female right before copulation.
They are primarily found in the western parts of Canada and the U.S. during the breeding season but can be found as far east as Ohio, Tennessee and the most northwestern tip of Georgia.
I have been hearing Lark Sparrows for a few weeks now and have seen them on the ground or up on top of the rocks on Antelope Island but I haven’t gotten any high quality images of them yet this year. They are only here for a few months but hopefully I will photograph some soon.
Life is good.
