THE OOLOGIST 



but during summer is scattered about 

 in suitable locations. Nests were 

 rather hard to find here as the birds 

 ranged about considerable in bushy 

 and grassy places. 



5. Nashville Warbler — Rather rare 

 spring migrant. Did not see it in the 

 fall. 



6. Parula Warbler — Arrives quite 

 early (April 12-21). Common migrant 

 and quite common breeder. Found 

 number of nests from 8 to 60 feet from 

 the ground. 



7. Yellow Warbler. Arrived April 

 17th to May 1st. Rather scarce. A 

 pair was found now and then about 

 thickets along the streams near fields 

 and farms. Not a common breeder, as 

 the country was hardly suited to them. 



8. Black-throated Blue Warbler — Ar- 

 rived late in April and not noted later 

 than May 20th. Not very common. 



9. Myrtle Warbler — This warbler 

 usually one of the commonest mi- 

 grants, was seldom noted here. Think 

 they must follow the larger yalleys 

 mostly during migrations. At my 

 home here in Warren they are abund- 

 ant in spring along the river valley 

 but are rarely seen on the mountains. 



10. Magnolia Warbler — Arrives about 

 1st of May. Not common as a mi- 

 grant and not noted later than May 

 20th. 



11. Cerulean Warbler — Arrives Apr 1 

 20th to May 1st. Common almost from 

 the day of their arrival; One of tin 

 most common of the breeding warb 

 lers. Can be heard singing anywhere 

 in woodland. Nests high and hard to 

 find except by watching the female 

 during nest building time. 



12. Chestnut-sided Warbler — Ar- 

 rives about May 1st and not noted 

 later than May 20th. Not at all com- 

 mon and only a few seen each season. 



13. Bay-breasted Warbler — Early in 

 May each season a few pass. Occa- 

 sionally a small flight. 



14. Blackburnian Warbler — Not com- 

 mon but a few were seen each season 

 during the early part of May. 



15. Black-throated Green Warbler — 

 Arrives from April 11th to 24th. Quite 

 a common migrant. 



16. Oven-bird — Arrives April 21st to 

 May 1st. Not common as a migrant 

 and- only a few pairs were found as 

 breeders. 



17. Water-thrush — Arrives early. 

 One season March 27th. Not very 

 common but a few pairs stayed 

 through summer and nested along the 

 streams in wooded hollows. 



18. Kentucky Warbler — Arrives last 

 week of April and is quite common 

 throughout summer. Found quite a 

 few nests but was never able to detect 

 the old bird in the act of nest-build- 

 ing. 



19. Mourning Warbler — Rare mi- 

 grant only noted a few times in early 

 May. 



20. Maryland Yellow-throat — Ar- 

 rives late in April and is quite a com- 

 mon summer resident. 



21. Chat — Arrives late in April. 

 One of the common birds in summer. 



22. Hooded Warbler — Arrives last 

 week in April. Quite common in sum- 

 mer and quite common breeder in all 

 suitable woodland. 



23. Wilson's Warbler — Rare migrant 

 only noted a few times in early May. 



24. Canadian Warbler — Regular but 

 not common migrant in early May. 



25. Am. Redstart — Arrives April 

 20th to 24th. Quite common and quite 

 a few pairs remain to breed.
