We have been assessing bird populations within the Tollway corridor using:

– intensive searches – walk on or off trail, documenting all species encountered (heard or seen)
– line transect surveys – walk a designated transect and document all species encountered
– circular plot counts – stand in a designated location for a fixed amount of time and document all species encountered
– mist netting

In addition to construction related surveys, we are studying many aspects of bird ecology:

Red-headed Woodpecker 
Migratory bird usage of Forest Preserves along I-294
North Chicago Wetland Mitigation Bank
Wetland birds in urban landscapes
Detecting cryptic wetland birds using eDNA
