NOTES AND QUERIES. 117 



that part of the Lee Estuary. It is, I believe, unusual for this species 

 to remain for any time where they may rest when on migration. 

 However, I think it may be assumed that this flock remained about 

 the harbour all through the winter. This species visits the east and 

 south coasts of Ireland much oftener than the west, where it is a very 

 rare visitor, and has come under my notice only on five occasions 

 during a period of forty years' wildfowl shooting in the Moy Estuary, 

 Killala Bay. In May, 1863, I was shown a beautiful specimen in 

 summer plumage, shot on the tidal part of the Moy between Castle- 

 connor and Ballina. On Nov. 6th, 1876, I secured a bird in immature 

 plumage by a shot from my punt-gun, by the same shot obtaining 

 one Bar-tailed Godwit, thirteen Lapwings, and thirteen Redshanks. 

 On June 29th, 1878, I observed a pair in the beautiful summer 

 plumage among a flock of Bar-tailed Godwits on the sands near 

 Bartragh, none of the latter showing any red. On Sept. 3rd, 1881, 

 I was shown an immature bird, shot by a young friend on the sands 

 near Eoserk Abbey. This is all the experience that I have had of 

 this species during my forty years' punt-shooting, and shows what a 

 rare visitor it is to our west coast, where the Bar-tailed is so nume- 

 rous, and many of them remaining all through the summer, none 

 leaving the estuary sands for their arctic breeding-grounds. — Bobeet

Incubation and Fledging Periods in Birds. — As records of the 

 periods of development of nestlings are even less frequent than 

 records of incubation — although surely not of less interest — it may 

 perhaps be worth while to set down what scanty notes I have been 

 able to make on the subject during the last few seasons. Incubation 

 periods are included for the sake of completion, though these are no 

 doubt fairly well known, in the commoner species at all events : —
