Before posting on last week’s Colorado trip I have one more topic from early June. If you’re a county lister or just want to know your local breeding birds, then you like to know where your local breeding species reside. One of the more difficult in our endless cornfield environment is Bank Swallow. But if there are rivers nearby then odds are there are breeding gravel or sand pit Bank Swallow.
My first encounter that Bank Swallows live in sand pits was noticing them in an old one by the Illinois River. The Bank Swallows would dig their nesting holes in the piles of sand by the river. I later noticed this happening at a small gravel quarry on a tributary river. The trick for the Bank Swallows was to make sure they picked a sand pile that wasn’t active. Or all their digging would be for naught!
When we moved to Indiana I started checking local sand pits. It didn’t take long to find them present at a large quarry in SE Johnson County. I couldn’t see the nesting holes so I waited on an adjacent road. It wasn’t long before they started flying over one, two, and three at a time.
Bank Swallows are fairly easy to ID if you can hear their Electric Call and to my eye they are noticeably smaller and a richer brown than other swallows.
I’ve also noticed they are the easiest to observe in mid-May when they are getting ready to nest. Or in late-July/early August when they’re grouping with other swallows to migrate. Otherwise they aren’t as active in the summer.
