on above trip several were procured." He also states in private 

 correspondence that he found them "Quite common May 30 to 

 June 4, 1884," thus locating the dates more exactly. May 14, 1905, 

 we saw two on our walk in along the east road. May 20-21, 190G, none 

 were observed; but the 30th of the same month the succeeding 

 spring three were noted. In the fall we have found the species still 

 more ahundant. In September, 19C5, six and two were noted or 

 taken the 5th and Gth, and another one the 10th. The first three 

 days of September, 1906, it was almost common and we were able 

 to secure as many specimens as we had any desire for. They 

 haunted the damp tangle bordering the eastern beach near Gard- 

 ner's and along the Cross-road, and were still more frequently met 

 with in the beds of Jewel-weed, closely adjoining, in the open spots 

 of the woods. By remaining quiet in such places we were able to 

 observe this interesting species at will. Though naturally shy when 

 we were moving about, when the observer remained perfectly quies- 

 cent they would approach almost within reach of the hand. As far 

 as we heard, they remained very quiet, uttering but the most com- 

 monplace little cheeps and those but rarely. On our return visit 

 the middle of the same month we noted but two single individuals 

 on the 17th and 18th. The fall of 1907, though we were present the 

 first few days of September, the time of their great abundance the 

 preceding year, owing to the general lateness of the early migrations, 

 they had not put in an appearance, as a species, up to the date of 

 our departure, September 6, though one was observed by Wood iii a 

 brush pile at the base of the final sandspit September 1st. This fall 

 there were no such masses of Jewel-weed anywhere to be seen, and 

 this may have had something to do with their non-appearance, the 

 early migrants, missing the congenial quarters of last year, passed 

 on across the lake without lingering. 



179. *Oporornis Philadelphia. Mourning Warbler. 



The Mourning Warbler is a rather uncommon migrant. In fact, of 

 late years, it has decreased so as to be even less common than the 

 preceding species. This condition, however, is not peculiar to Point 

 Pelee, but applies equally to our Detroit stations. None were noted 

 May 13-14, 1905, and but one May 21, of the succeeding year. May 

 31 and June 1, 1907, however, we were more fortunate and five and 

 one were noted on the respective days. They sang freely with a 

 song much similar in quality to that of the Connecticut, but hardly 

 as throaty, and differently accented. Fall dates on this species are 

 difficult to get and greatly to be desired. We always supposed that 

 they slipped through very early and so passed unobserved. This has 

 been corroborated by the data we have been able to gather the last 

 two years at Pelee. Keays noted one September 17, 1901, and we 

 took another September 3, 1906, with the Connecticuts, in the Jewel-
