MAPS Visit 3 – Blue Lakes

Yellow-throated Vireo (Seabrooke Leckie)

Visit three to Blue Lakes happened late last week. A definite highlight of the day was the capture of three adult Yellow-throated Vireos (2 new and 1 recap) and the discovery of a nest with young in the crown of a large Red Oak near net 1! We’ve banded the male and female tending the nest but also captured a new gravid female (carrying egg) in net 1 around mid-morning. We suspected at least a couple of pairs were in the area but the appearance of a gravid female so close to the nest of another pair seems rather curious. Very cool to have this species around and in numbers too!

The morning’s work went smoothly and a steady trickle of birds were handled over the six hours. Despite that multiple territories of Black-throated Blue Warblers are present within the station boundaries, we have only managed to band and recapture the one male and female individual. We are starting to wonder if the other singing males are unpaired.

We’ve now completed nine visits to all three stations combined and are not even halfway through the season! The remaining visits to each station will be interesting as adults move or reestablish territories and this season’s crop of young birds begin to disperse. The month of June was extremely wet and it remains to be seen how this has affected nest success for landbirds in Frontenac County and beyond….
