I have seen 3 Indigo Buntings at the same time around my feeder this
year. And one rose-breasted grosbeak who only stayed for a few days.
I heard the summer tanager for only two days, but they've gone.
The other day on my feeder, at the same time, were a male Indigo
Bunting, a male Goldfinch, a male Cardinal, and hanging on the suet
block (which hangs off the feeder) was a male Hairy Woodpecker. It
was SO impressive to see black/white and the three primary colors.
