TRA-912: BARN SWALLOW (HIRUNDO RUSTICA) NESTING HABITAT, USE OF BRIDGES AND CULVERTS AND OTHER STRUCTURES, AND IMPLICATIONS TO INFRASTRUCTURE PROJECTS IN ONTARIO
Barn Swallow is a medium-sized song bird that is approximately 15 to 18 cm long, which feeds on flying insects. They are easily recognized by their blue glossy back and upper wings, rusty- orange forehead and throat, brownish underbelly, and their deeply forked tails. In Ontario, they are most commo...
