met it during the springs of 1901 and 1902 at Port Huron, and Mr. 

 Saunders regards it as not uncommon at London. We met the 

 species in limited numbers in May, 1905 and 1906, at Point Pelee. 

 It seems then that Detroit is carefully avoided by this bird in the 

 spring and is an indication of the peculiar situation this section 

 occupies migrationally. 



Thryothorus ludovicianus. Carolina Wren. — August 11, 1906, 

 we added this species to the Wayne Co. list when Mr. Taverner 

 took a juvenile male near Palmer Park, on the outskirts of 

 Detroit. We were first attracted by its clear, bubbling, liquid 

 notes proceeding from a tangle of blackberry canes. Though a 

 young bird it is not sufficient to found even a hypothetical breeding 

 record, as it could fly perfectly and might have come from almost 

 any distance. It is rather interesting to note that most of the 

 extralimital cases of this bird's occurrence in the adjoining sections 

 have been in the fall, and seem to indicate that this species has a 

 tendency to wander north after the breeding season, as do the 

 herons and some other birds. It may be explained by the fact 

 that all birds are more numerous in the postnuptual than in the 

 prenuptual season, due to the great numbers of newly raised young. 

 There may therefore be greater chances of rare birds being seen 

 then. For various reasons, however, we incline to the former 

 than to the latter explanation. For one thing, the same movement 

 seems to occur in the Cardinals and hitherto more adults have been 

 observed here in the fall than immatures. 



Sitta canadensis. Red-breasted Nuthatch. — This little 

 nuthatch is something of a puzzler. It is a migrant here, yet we 

 understand that it winters in the Upper Peninsula. With us it is 

 extremely erratic in its appearance, being common some years 

 and then absent for several years in succession. This fall (1906), for 

 the first time in some years, it was common. The first specimen 

 was seen in the city August 30. September 1 to 3 they were com- 

 mon at Point Pelee, and still more so from the 15th to the 22d, 

 and October 15 vast numbers were seen there. They were every- 

 where, in the hard woods, hanging head downwards from the tips 

 of the long branches, in the orchards, creeping over the trunks, 

 and in the red cedar thickets ; but by far the largest numbers were 

 towards the end of the Point on the edge of a waste clearing where
