Aēx galericulata. of another female towards the coveted drake. January 30, 1911. The original pair of Mandarins are in high plumage and have been so for some time. A second pair which I bought some time ago are also in high plumage although cagoworn. February 19, 1911 Both pairs of Mandarins are in high plumage and each jealous of the other. It is ridiculous to see each of the drakes on opposite sides of the pond or on the same side, swell up and make their hissing bubbling calls as they show off. They lean back so far that they look as though they would fall over backwards. The first drake often gets mad and chases the other about when he calls or "blows bubble" under his wing. The females exhibit considerable jealousy towards each other and towards the males not their mates, darting their heads out at them when they come close. Often when a drake is showing off and making his rapid hissing calls, his mate will pick the feathers on the side of his head, apparently in a caressing manner. March 14, 1911. The first drake does not show off as much now that I have gotten rid of the second pair.
