Taverner and Swai.es — On Point Pelee Birds. 83 



mixed flock of Barn and Bank Swallows. Several May 20, 1906, and 

 abont five September 1, 1900, on the telegraph wires at the base of the 

 I'oint. None noted the May-June trip of the following year, but from 

 August 24tli to the 31st, from two to ten were seen each day, Init none 

 in September. Not noted May 1-4, 1908, when Wallace and Swales 

 made a trip. This is by no means an abundant sjioi'Ies in this sec- 

 tion. Its reddish tan.nunp makes a conspicuous and certain field 

 mark when the bird is in flight. 



145. *Hiriii)(1o cryflironastra. — P>arn Sawllow. 



A common sunnner resident. Common on all May dates. In 1905 

 the last were noted Sejitendier T), when considerable nund)ers were 

 seen. In 190S they were eonnnon the first three days of September, 

 and about twenty-five were noted the l.lth, and about ten the 19th. 

 In 1907 they were still common and migrating heavily up to the time 

 of our leaving, September 0. 



14('>. *Ifi(l()2)fOCiiG hicolor. — Tree Swallow. 



The Tree Swallow we have found practically common on all" May 

 dates. In the fall it has never l)een abundant. In September, 1905, 

 a few were noted daily from the 4th to 11th, on which latter date 

 several flocks were observed passing over. September 18, 190G, three 

 were seen, making our only record for the locality that season. In 

 1907 from one to eighteen were noted from August 24th to the 30th, 

 and no more after that. There has been a considerable diminution 

 in the abundance of the fall flocks of this species in this section of 

 late years. 



147. *l\rpari(i riparia. — Bank Swallow. 



Connnon on all May visits. In 1905 the last fall flock was noted 

 September 11. In 1900, common the first three days of September, 

 and not seen during our return visit in the middle of the month. In 

 1907, great numbers were seen the latter end of August from the 

 24tli, irregularly diminishing to the time of our departure, Septem- 

 ber 0, when but several were noted. A few seen May 2, 1908. 



148. *Stel(n(lopieryx scr)-ipcn}iis. — Rough-winged Swallow. 



One of the many interesting events of our fall trip of 1907 was the 

 nund)er of Rough-wings seen migrating from August 24 to September 

 2. They were generally mixed in with large flocks of Bank Swal- 

 lows, and nearly every time we closely scrutinized the latter we 

 found numbers of the former among them. We counted and esti- 

 mated the number of Rough-wings seen on these various days as 20, 

 100, 15, 4, 2 and 10. If the same proportion of this sjiecies existed 

 in all the flocks of Bank Swallows the nundier of this usually rare 

 species that passed over the Point must have been very great.
