How Many Black Birds in the Tree

There was I in the garden sitting in the Sunshine, Mica chewing on her Kong enjoying the warmth. I hear the sound of the pond water fountain; I hear the birds sing while going about their business. Then I see a female black bird with a green caterpillar wriggerling in her beak. She hops into our Conifer trees, and I hear chirping. In and out of the trees the male and female Black birds go, feeding their little ones. Then I got the chance when they both took time out from feed the young, and snap this little picture. Are little darlings.
