These are very common about Derby. Every morning a 

 flock of some four or five hundred arrive about 11 a.m. and 

 remain till about 5 p.m. The trees are white with them; and 

 when they pitch on the smaller ones the effect is like a May- 

 tree in full flower. All at once they take to the wing 

 together, looking like snow, driven before a high wind; occa- 

 sionally some 20 or 30 come down to the lagoon to drink, and 

 then they seem 'to increase the number of water-lilies. -\ They 

 are a noisy bird, and seem always on the lookout. When one 

 is wounded and on the ground shrieking, others come round 

 their fallen comrade.
