Les, If you follow those Purple Martins, you will likely find their nighttime roost. It can be quite impressive, we had one here in Salisbury in the mid-'80s that had upwards of 30,000-50,000 birds. Typically the birds will mill around the roost site until almost dark and then in a period of only a few minutes swoop into the roost. On one occasion at the Salisbury roost, the birds didn't even appear in the roost area until 15-20 minutes before dark! This was very unusual. We thought the birds had left for the season, but they showed up. The birds will likely stick around the roost until the last week of August. Some birds might even stay until mid-September. >While at my daughter's soccer practice tonight at the National Guard >Armory fields in Havre de Grace, there was a constant stream of Purple >Martins heading south from 5:30 - 7:30 PM.
