THE OOLOGIST. 



27 



on a small island of mud at quite a dis- 

 tance from the mainland. Eggs very 

 light, nest composed of water grass. 

 Every night while lying in camp we 

 could hear the wearying cries of the 

 Loons out on the lake. 



Spotted Sandpiper. No nests were 

 found but young birds in the down 

 were observed and old birds could be 

 counted by the hundred. 



Downy Woodpecker. One nest was 

 found containing young in a white birch 

 stub leaning out over the water of the 

 lake. 



Red-winged Blackbird. Nests were 

 found containing eggs of this species 

 built in low bushes in marshes back 

 from the shore of the lake and many 

 birds of this species were observed. 



Baltimore Oriole. This species was 

 breeding. Nests with eggs were found 

 bnilt in old apple trees near the shore 

 of the lake from fifteen to thirty feet 

 from the ground. 



Vesper Sparrow. Several nests with 

 eggs were found. 



Song Sparrow. This species was the 

 most abundant of any species of Spar- 

 row found breeding at the lake. Many 

 nests with eggs were found on Lath- 

 rop's Island, the largest island in the 

 lake. I found a nest of this species at 

 the water's edge built in a mass of dead 

 water grass and driftwood and com- 

 pletely roofed over and concealed from 

 view. It was found by flushing the 

 bird from the nest that it contained 

 four eggs, which was the usual number 

 found in all of the nests we observed of 

 this species. 



Tree Swallow. One nest of this spe- 

 cies was found near the mouth of Dead 

 River back a few rods from the water. 

 It was built in a maple stub nearly fifty 

 feet from the ground. The stub was 

 honeycombed with holes made by 

 Woodpeckers, but only one pair of 

 Swallows was seen. They were seen to 

 fly to a hole near the top of the stub 

 and were, as near as we could tell at 



that distance from the ground, feeding 

 their young. 



Yellow Warbler. The most abund- 

 ant breeder of any species found at the 

 lake and river. Its nests were every- 

 where found, built in low bushes near 

 the water at a height varying from two 

 to fifteen feet from the ground; eggs 

 commonly three and four in number. 

 Mr. Teague found one nest containing 

 five eggs on the banks of Dead River. 

 Its nests could be counted by dozens 

 while the birds could be seen by hun- 

 dreds. 



Oven Bird. One nest was found 

 near our camp which contained five 

 beautiful eggs. It was a typical nest of 

 this species. 



Maryland Yellowthroat. Two nests 

 were found on islands in the lake built 

 in low bushes. One contained three 

 eggs the other four. No birds of this 

 species were seen. 



American Redstart. Several nests 

 were found built in low maples and al- 

 ders from 8 to 13 feet from the ground. 

 Eggs three and four in number. 



Catbird. Very common breeder; 

 nests in low bushes; eggs three to four 

 in number, commonly four. 



Wilson's Thrush. Nests of this spec- 

 ies were found on Lathrop Island and 

 the banks of Dead River containing 

 eggs and young. It was identified as 

 this species by Mr. Teague and no oth- 

 er species of Thrush was seen at the 

 lake. Nearly all of the nests contained 

 four eggs each. 



Following is a list of the birds seen at 

 the lake and river but not found breed- 

 ing: 



Black Duck. A few seen, breeds 

 quite abundantly in the latter part of 

 June and in July. 



American Bittern. Several birds of 

 this species were seen. 



Great Blue Heron. One or two seen 

 near Lathrop's Island. 



Ruffed Grouse. Several were seen 

 near the lake shores.
