Field Notes. 79 



Great Northern Diver at Castleton in Cleveland. — On 



November ist a Great Northern Diver was captured in an 

 exhausted state in a small stream near Castleton in Cleveland, 

 which is twelve miles from the sea. The bird had no visible 

 injury, nor was it in poor condition, neither had there been 

 any October gales which might have driven it so far inland. 

 Possibly it may have got lost in some of the dense fogs which 

 prevailed at the time. Dr. Chalmers, of Castleton, acquired 

 the bird, and has preserved and set up the skin. It was a 

 very handsome adult male in nearly complete summer 

 plumage, measured thirty-one inches in length, spread of 

 wings fifty-two inches, weight exactly six pounds. — F. 

 Snowdon, Whitby. 



Little Auk at Barmby Moor, near Pocklington. — A 

 Little Auk in a very exhausted condition was picked up on 

 the farm of Mr. A. Richardson, on November 23rd, 1920. 

 This bird, which had evidently become lost in the fog pre- 

 vailing at that date, was placed on a pond, but died during 

 the night. I saw it just before it was sent to Messrs. Allen, 

 of York, to be stuffed. — Sydney H. Smith. 



A correspondent in The Yorkshire Post of November 30th 

 records another specimen at Wrelton, near Pickering, and in 

 the same paper for December 4th is a record of three specimens 

 obtained in the valley of the Ure in February, 19 16, ' one at 

 West Witton, alive, but very done up ; one at Appersett, and 

 one near Honeycott, above Hawes. These were both dead. 

 There was a snowstrom with easterly gale at the time.' — R.F. 



Behaviour of Hobby in Kent. — This bird acted very 

 differently on occasions here during 1919, which showed that 

 no hard and fast dogmatic statement can be applied to its 

 behaviour. When standing near a hedge, one passed me and 

 settled on the ground about five yards away and waited about 

 four minutes opposite where some Sparrows were in the hedge. 

 As these showed no signs of emerging, it flew quietly down the 

 hedge and then over a field. On this occasion it could not fail 

 to have seen me as it looked at me several times, but showed 

 no alarm. Later on, a Hobby behaved very differently as it 

 always took flight as soon as it saw me, even though 20-35 

 yards away and without a gun. Later still in the year, I 

 saw a Hobby at a distance walking on the ground among some 

 fruit trees, and approached to see what it was doing. Although 

 I had no gun at the time, the Hobby now hid itself behind a 

 bush on seeing me approach, and remained hidden for a time 

 while I was looking about to see where it had got. After 

 searching about, it finally flew out close to me and made 

 rapidly over the fields beyond. It is, of course, impossible 

 to be certain whether this was the same individual on all 

 occasions, but there was no doubt about the species. Com-
