NOTES AND QUERIES. 397 



large bird following the few Swallows as they hurriedly flew towards 

 their autumn roosting-place in the reeds by the river, and, if I mistake 

 not, it was a Hobby, but the quick movements of the bird in the 

 increasing dusk prevented a certainty of identification ; such a habit 

 would not be at variance with what I have before recorded of this 

 handsome little Falcon. — GK B. Cobbin (Eingwood). 



"Birds Nesting in Andalusia." — My friend the Eev. F. C. R. 

 Jourdain, who was with us for a part of the time in Andalusia, wishes 

 me to make the following Corrigenda et Addenda to the list of species 

 seen in 1905, published in the last number of ' The Zoologist ' (ante, 

 pp. 326-28) :— 



Corr. — Melodious Warbler ; dele reference to eggs. 



Add. — Western Olivaceous Warbler (H. opaca) ; eggs, May 11th.

 Little Owl. Montagu's Harrier. Stone Curlew. Avocet. Dunlin. 

 Oystercatcher. Grey Plover ; April 20th. Lesser Tern. L. melano-

A Query. — Despite the constant attention which observers like 

 Mr. Oldham are bestowing on the habits of the Noctule, there still 

 remain several doubtful points in its life-history. We know, for 

 instance, that the sexes fly together, but how do they assort them- 

 selves during sleep or hybernation ? Was the late J. H. Grurney right 

 in suggesting that the colonies are often composed of a single sex ? 

 Again, what is the colour of the newly-fledged young ? Are they of 

 the same tints as the adults, or are they darker ? Any information, 

 however slight, which any reader of ' The Zoologist ' may be able to 

 publish on these questions would certainly contribute towards a more 

 complete knowledge of the natural history of this fine Bat. — G. E. H. 

 Babbett-Hamilton.
