Mourning Dove, Bluejay & ?? ( photo / image / picture from gfreiherr's Garden ) mystery guests up close ( photo / image / picture from gfreiherr's Garden ) Haven't seen these two are the feeder, do you know what they are? Is the bird eating upside down a nuthatch? ( photo / image / picture from gfreiherr's Garden ) Need help identifying both of these birds.
The first ones are immature male Red-winged Blackbirds. They in the same Family as Grackles but different Genus and Species. The ones that visit my yard appear to wander a lot, they are here in the spring and fall but somewhere else most of the year....in other words they don't tend to hang around and cause problems like the Grackle. The last one is a White-breasted Nuthatch. They are usually found in forests but I guess your birdfeeder was just too much temptation for that one. They like insects and large meaty seeds.
White breasted nuthatch is at my feeder daily. Grackle family swams aroung pretty often now, visiting the grape arbor.
