THE BIOLOGICAL REVIEW. 65 



as soon as the lakes open in the spring the ducks leave the 

 rivers and take to the lakes. 



(May 24, 1889.) I collected a pair of the Water Thrush 

 (Seiiirus noveboracensis), the only specimens I'ever saw here- 

 The Golden Crown [Seiurus aurocapillus) is not uncommon, and 

 nests with us. 



I collected a c? Yellow-bellied Woodpecker, which was of a 

 bright amber color on the belly, and all that ought to be white^ 

 on the back and wings of an amber color also. I also got his- 

 mate, and her crown was pure black without any red. 



I found a nest of the Red-breasted Nuthatch (Sitta cana- 

 densis), with young about ready to fly. It was built in a rotten 

 stub, about five feet from the ground, and around the hole there- 

 was a ring of pine or balsam gum plastered on the stub. I 

 thought it was put there to catch ants, flies and other insects, 

 so that the young ones might learn to provide for themselves, 

 for I noticed them pushing out their heads and pecking at the 

 gum. I have found three nests of the Chicadee {Parus atrl- 

 capilhis), and they were all lined with the wool of the wild 

 rabbit. 



(May 3, 1890.) To-day I saw a lot of Black and White 

 Warblers (Mniotilta varia) for the first time this spring, and 

 also some specimens of the Black-throated Green Warbler 

 {Dendroica virens). 



The Fox Sparrows came on April 17, and disappeared about 

 the 29th. I saw a solitary one to-day. I also saw a flock of 

 Wild Geese and many Gulls flying southward. Doubtless the 

 very cold weather we are having has caused them to return. 



(May 6, 1890.) I collected a fine d D. virens; they are 

 feeding on some kind of insect which they find on the foliage of 

 the hemlock trees. They flutter over the boughs, making a 

 snapping noise with their bills, and then dart in and catch an 

 insect. They have the ability to run up and down the trunks 

 of trees, like a Tree Creeper, but you do not very often see 

 them doing it. 



The Ruby-crowned Kinglets are now singing, they have a 

 peculiar and very sweet song. I have seen these birds many 

 times, but never heard them singing until a few days ago. They
