This morning I had two interesting birds together in a tree right
outside my window: a Wilson's Warbler and a Black-throated Gray
Warbler. I believe these are both new "yard birds" for me after 20
years of living here (my records are not digital and hard to look
up). Any speculation as to why they arrived today?
