Hiking the Bruce Trail & side trails in and around Silver Creek Conservation Area (Georgetown area) today, I was rewarded with a couple of nice (and unexpected) birds: Yellow-billed Cuckoo and Yellow-throated Vireo. Unfortunately I had to be satisfied with their songs, because both were well hidden in the leaves. I also heard an Eastern Phoebe (presumably on territory) at the edge of the Terra Cotta CA. I did manage to see 2 of at least 3 Scarlet Tanagers.
Another "yellow" was my first Tiger Swallowtails of the year.
