--Boundary_(ID_/ZfxrqTphl/XTbxBHzC8Ag) Content-type: text/plain; CHARSET=US-ASCII; delsp=yes; format=flowed Content-transfer-encoding: 7BIT I'll differ a little from Richard, to say that juvenile and immature bald eagles in first and second years are extremely variable in how many white markings there are and where they are, but the wing linings (not just the axillary/armpit area) always show a lot of white on the underside of the wings, in marked contrast with the mostly dark other wing feathers, and this will rule out golden eagle. Swainson's hawk, on the other hand, has a lot of whitish making up the wing linings and a lot more, in contrast with the dark flight feathers.
