What a beautiful bird, and those nests are facinating. Birds never cease to amaze me in the home building skills. We saw a swallow nest a few months ago which was built up under the eves of a house which was rectangular in shape. The sides were perfectly straight and a perfect rectangle. Really sturdy, holding 4 babies until mature to fly away. Then a new family came with new eggs and babies. Facinating! Great shots, thanks for sharing :)
