The fledglings are NOISY! All the typical baby behavior - wing flutter, clumsy landings, and incessant zheee-zheee-zheee begging call. When Don and Lillian Stokes said "This is a very conspicuous time in the birds' life cycle", they weren't kidding! (Stokes Guide to Bird Behavior Volume II).
Both mom and dad help raise the young. Around here, they've been feeding them live mealworms we've put out for them. To the feeder - to baby - to feeder - to baby - and so on. I've been adding 20 or so mealworms to the APS® Side Dish multiple times each day. They've also been hitting the peanut feeder and peanut suet hard.
I've seen 6 or so young around. I think the differences between the adult and young are quite subtle. The forehead patch of the young titmouse is more grey than black; though the young I've seen look mostly black. I think the forehead patch is somewhat smaller than on the adult.
The fledglings may continue to get food from parents for four weeks or more and will remain with their parents through winter. The family bond is strong. Young will stay with their parents, and have been known to help them raise young the next season.
We in upstate New York are beneficiaries of the expanding range of the Tufted Titmice. Eaton's "Birds of New York" published in 1914 stated, "This species inhabits the warmer portions of the eastern United States from Nebraska, Illinois, Ohio, Pennsylvania and New Jersey to Texas and the gulf coast, occasionally straggling to Wisconsin, Michigan and Connecticut. In New York it is confined to the warmer portions of the Carolinian district as a breeding species...I have found no records of its breeding in the interior of the state." (emphasis added)
