Yesterday, we heard the Eurasian Jay (Gaio) shrieking in our lilac tree. Then she flew, in all her glorious color to the big maple tree in front. Then we wanted to hear the shriek again. We found probably the best site on the net for birds, The Cornell Lab of Ornithology. On this page you can hear (click sound) the blue jay a bird I saw alot when I lived in Boston. His shriek is very similar to the Eurasian Jay.
