398 NOTES ON THE 
They have a simple note which is aimost constantly repeated 
in a subdued tone, which sounds somewhat like keet. I am 
informed that quite a number of local collectors have obtained 
the species form time to time. Dr. Hvoslef reports them pre- 
sent at Lanesboro, June 1st, 1882.

GEOTHLYPIS PHILADELPHIA (Wrtsoy). (679.) 
MOURNING WARBLER. 
This is another species of the tardy genus Geothlypis, that 
has been identified, but whose habits have remained quite 
obscure. I obtained a single individual in typical plumage, on 
the first day of June, 1869, very nearly within the city limits. 
Since then I have met occasionally migrants in autumn, and 
have a few reports from competent correspondents. Dr. Hvos- 
' lef obtained one in high plumage on the 25th of May, 1884. 
Several local collectors claim to have obtained specimens sey- 
eral years earlier. Mr. Washburn searched but did not find it 
where Coues found it previously, ‘‘ breeding abundantly along 
the Red river.” Their early southern movement may explain its 
absence at the time the former was in that locality. Mr. Trippe 
had, somewhat earlier, found it breeding prolifically inMinnesota, 
but failed to find the nest. He ‘‘repeatedly saw the old birds 
feeding the young in the latter part of June and early in July,” 
which makes its local breeding assured. He further says:— 
‘“‘They are similar in their habits to the Maryland Yellow- 
throat, but are not so exclusively devoted to thickets and un- 
derbrush, frequently ascending to the tops of the tamaracks, 
for which they show a great predilection.” It is to be hoped 
that more facts regarding its local history may ere long be 
obtained. Coues says:—‘‘ The nest is rather slight, but a neat
