The Welcome Swallows usually migrate away from our area in about March, as far as I can tell (based on my casual observations of when I no longer observe them).
This year they are still about in the last week of May (and for who knows how much longer?)
Although the nest in my carport fell down last week. Poor sods will have to rebuild again next season.
Anyone else seeing unseasonal activity in the Welcome Swallows department?
