[April 
Dendrceca striata (Borst.) Bd. May IO a few males arrived, 
but no others were noticed until the 18th. The 19th and 20th a 
few were seen; the 21st they became quite numerous, and from 
the 22nd to the 24th they outnumbered the other species. On 
the 25th, however, the numbers were exceeded by those of D. 
castanea , but the flocks continued quite numerous until after the 
27th, after which date only a single straggler was noticed, on 
June 5. The first female arrived May 21. 
Dendrceca castanea ( Wilsi) Bd. May 18 five males of 
this species appeared in a large flock of other Warblers. The 
number gradually increased, and May 23 it was only exceeded I 
by D. striata. May 25 it outnumbered them all, but the day 
following none were seen. The females first arrived May 25. 
Bendrosca pennsylvanica (L.) Bd. A small flock arrived 
May 3, but none were noticed again until May 8, when several 
others were seen. The number gradually increased, and May 12 
it was only exceeded by Setophaga ruticilla. May 14 it out- 
numbered them all ; from this date, however, the flocks gradually 
decreased, although many remained to breed. The first egg was 
taken June 3. 
Bendrceca maculosa ( Gm .) Bd. May 3 a single male 
arrived. May 5 a few were found in the other flocks, but none 
were noticed again until the 9th. A few were seen during the 
following days, but from the 13th to the 17th none were noticed. 
On the 1 8th, however, this Warbler rather outnumbered the 
other species then present, and continued very numerous until 
May 24. The last were noticed May 25. Two males, shot May 
5, had the black of the head not continuous with that of the 
back but plainly interrupted with clear ash. 
Dendroeca tigrina (G?n.) Bd. May 8 quite a number of 
males arrived,, scattered through the different flocks, and the next 
day large flocks arrived, in numbers almost equaling Setophaga 
ruticilla. They remained quite numerous, and on May 12 it 
was only outnumbered by S. ruticilla , D. pennsylvanica , and 
H. rujicapilla. May 13, however, only a few were seen, but 
May 14 large numbers again appeared; afterwards only a few 
were noticed, mostly females. May 17 and 18 none were seen, 
and for several days only one or two were noticed, the last one, 
May 25. The first female was seen May 9th. Several males 
taken had spots on four pairs of tail feathers.
