58 BRITISH BIRDS. [vol. xv. 



very doubtful breeder in north Lincolnshire, but there is 

 slight evidence that it may do so, for I recorded one on 

 March 31st, 1919, in British Birds, and I now record another 

 on April 26th, 1921, at exactly the same spot to a square yard. 



They do not nest at this spot, but on these dates this bird 

 should not be far from its nesting locality. 



The above notes are all from my own personal observation.

HOUSE-SPARROWS NESTING IN HOLE OF LESSER 



SPOTTED WOODPECKER. 

 With reference to Mr. Aplin's note {antea, p. 44), on House- 

 Sparrows {Passer d. domesticus) attacking a pair of Lesser 

 Spotted Woodpeckers [Dryohates minor comminutus) at their 

 nesting hole with a possible view to appropriating the same, 

 I found this summer a pair of Sparrows breeding in what 

 appeared to be a typical Lesser Spotted Woodpecker's nesting 

 hole about 10 feet from the ground on the under side of a 

 nearly vertical dead branch of an apple tree in an orchard. 

 The hole was much too small for any species of Woodpecker 

 but the Lesser Spotted, and they are not uncommon in the 

 neighbourhood where the hole was observed, near Abermule, 

 Montgomeryshire. W. M. Congreve. 



WOOD-LARK BREEDING IN MONTGOMERYSHIRE. 

 With reference to my note (Vol. XIV., p. 132), in which I 

 stated that I hoped actually to find a nest of the Wood-Lark 

 (Ltdlula arhorea) this year, I am sorry to say that I have 

 completely failed to find a nest, but have quite satisfied 

 myself that they breed sparingly in the county. I have come 

 across them, the males in full song, in three different localities. 

 On two occasions pairs have been watched, and one pair, only 

 a few hundred yards from my house, was under observation 

 for nearly a month. On April 26th this pair showed signs 

 of alarm, and I found what appeared to be the commencement 

 of a nest in a tuft of coarse grass and dead bracken on a sunny 

 hillside. It was a deep neatly rounded hollow, and contained 

 four or five black horsehairs. To my disgust, I never saw 

 this pair again after this date, and can only presume that 

 they resented being watched or else one of them fell a victim 

 to a Kestrel {Falco t. tinnunculus), which frequented the 

 neighbourhood. W. M. Congreve. 



LATE SPRING MIGRATORY MOVEMENT OF 

 COMMON WHITETHROATS. 



On June 20th, 1921, there was a large immigration of Common
