First Hummer & Weigela, Wine & Roses
It sounds like the ruby-throats are arriving late up north. Mine did too. Lat year it was the last week in April; this year is today. Anyway, I heard chattering out back and knew what it was.
Someone also asked about Weigela Wine & Roses once here. The images below show an example of one in bloom where the hummer was chattering.
