Make sure to lightly sketch the base with a pencil, as you’ll want to erase it later. Birds with longer wings generally have longer arms and shorter hands, like wandering albatrosses or seagulls. Smaller birds have shorter arms and longer hands, like sparrows or hummingbirds.
Don’t forget the skin flap between the forearm and the upper arm.
Eagle wing feathers look like “fingers” but this doesn’t apply to all birds, for example budgerigars.
