MIGRATORY BIRDS. 



NOTICE OF THE ARRIVAL OF MIGRATORY BIRDS IN NORTH OXON. 

 IN THE BPRING OF 1881, WITH NOTES. 



The first migrant I observed this year was on March 29th — a fine 

 male Wheatear. It was ainging from the top of a tall hedge when I 

 first saw it, but soon went off on the fallow. This bird is by no means 

 common here, and only visits us in early spring, and again in Septem- 

 ber. Tlu; next day I examined at Wyatt's, the Banbury bird-stuffer, a

 April ( Jth — very late — since then they have been plentiful, and are still 

 in song. Willow Wrens appeared on the 18th. This is a very 

 common species with us ; I saw hard set eggs on May '2.'5rd. Three 

 Swallows were seen at Bodicote flying round some apple trees on 

 the 17th. and on the same day I heard the Wryneck. On the lnth I 

 noticed five in- six Redstarts, they had evidently just arrived; also a 

 Common Whitethroat. The Cuckoo was heard on the 23rd, about 

 late. A Whinohat, T an told, was seen at the brick-pits, 

 Banbury, on the •-'•"ith. A few pairs of this bird may be found 

 ohiefly along the railway banks, but they are not very common. 1 did 

 me across the Yellow Wagtail till the 28th, when I saw one on 

 the telegraph wins. Strange to say this is a very favourite perch of 

 thehh forth Whitethroat. <>n the 30th, a pair of Black-
