our resident Birds, and have passed on to their moreNorthern 

 haunts : an opinion which will also account for the fact, that 

 a few will sometimes make their appearance long after all 

 our resident Birds seem to have left us ; and I have myself 

 witnessed the arrival in a state of exhaustion and fatigue, 

 from the broad expanse of the Ocean, and late in the Au- 

 tumn, of small flocks of Martins, that seem to have had their 

 passage interrupted by boisterous opposing winds. The 

 latest date given for the disappearance of these Birds, refers 

 to the year 1835, and belongs to a considerable flock of our 

 own Birds ; which sometimes disappeared for a few days 

 and then appeared again, still continuing a recognition of 

 their former residence. Towards the end of their stay, the 

 weather being cold, they passed the night in holes of a wall 

 originally formed for scaffolding. 

 BANK MARTEN. H. Riparia. Jenyns, p. 158. Be- 

 wick's Br. B., vol. 1, p. 263. In Summer, local ; there

 B., vol. 1, p. 266. Common in Summer. First appearance 

 from May 1st, to the 21st, the whole colony appearing to- 

 gether, contrary to the custom of the other Hirundines. 

 Latest seen from July 28tb, to August 16th. Their num- 

 bers suffer no increase, in a considerable number of years ; 

 and indeed all the Swallow tribe appear to suffer a diminu- 

 tion of numbers when absent from us.
