Remsen, J.V. 1974 Bald Eagle Haliaeetus leucocephalus Feb. 17 Calif. Valley-Carrizo Plain, San Luis Obispo Co., Calif: 1; soaring with 2 Golden Eagles on a salt bush plain, gradually climbing up with a thermal and moving north. This or another bird was seen 3-4 miles n. of this spot 15 minutes later. This was a good opportunity to study the differences in shape between the two eagles - Bald has much greater proportion of its body in front of its wings and less behind - it has a shorter, broader tail, broader wings, and a conspicuous larger, more hooked bill - the latter was visible at hundreds of yards. Tiern NWR, Tiern Co., Calif: 2; in view at once, both moving north. Dec. 28 Barr Lake to Muir Sgs, Colo: 5q 2i lu in Muir Sgs- Jackson Lake area,
