A group of tree swallows is called a flight or a gulp. 
 Our flightof tree swallows in the wildlife sanctuary is a joy and wonder. Every spring they return from their wintering migration to mate, and nest here at the santuary. This location at the summit, where we have a mix of forest, big open meadows and close proximity to the Keen Creek Resivoir is one of thier favorite spots.  
 
If you would like to sponsor a new nest box I will install it in a prime nesting spot in the sacntuary and send you a photo of the tree swallow family that moves in.
