May 22 2023 (Monday) Ottawa Spring Migrants

Leader: Bernie Ladouceur.

Twelve participants including, the leader, found 86 species. Once again, this 
half-day trip explored the Lac Deschênes IBA.

After we met at the Lincoln Fields Shopping Centre, where we had our only House 
Sparrow of the day, we headed to the Britannia Conservation Area (Mud Lake). 
Here we found 59 species in just under three hours, including 16 species of 
warbler. We were patient to get good views of a number of them, including 
Tennessee, Magnolia, Bay-breasted, Blackburnian, Blackpoll, and Wilson’s 
Warblers. Other highlights included a heard-only (for most) Mourning Warbler, a 
late-migrating Blue-headed Vireo, singing Swainson’s and Wood Thrushes, and a 
flyby Gadwall.

Next, was a short stop at the Shirley’s Bay boat launch. An adult and a 
yearling Bald Eagle, and a Common Loon were the highlights.

Finally, we walked a good length of the Greenbelt Pathway West (about 3.7 kms 
round trip), starting at the Carling Avenue entrance and ending at the start of 
an extensive field north of Highway 417. At both ends of the walk, we were 
treated to a good show by Bobolinks, with Eastern Meadowlarks joining in at the 
start of our walk, and a Northern Harrier putting in an appearance at the far 
(south) end. In between, the trees progressively became taller; highlights 
included a drumming Ruffed Grouse, a cooperative Green Heron, a persistently 
singing Brown Trasher, plus excellent views of both male and female 
Rose-breasted Grosbeaks and Scarlet Tanagers. The female tanager was especially 
accommodating because she was continually returning to a caterpillar “tent” to 
collect nest material (nice, because it’s in my atlas square!).
