6. After the latter date it was observed occasionally at different 

 places in the sand region. 



122. Sitta carolinensis. "White-breasted nuthatch. ^ — Michigan: 

 Common resident, breeding all over the state. 



A rare breeder in the region. Observed at several places between 

 Sand Point and Hat Point, and a single bird on Stony Island. Not- 

 withstanding the fact that there were many apparently suitable 

 cavities for them to nest in, onl^^ a very few of these birds were seen 

 during July. It was seen more often after the young made their 

 appearance, about August 1, but never became common anywhere 

 in the region. The single bird seen on Ston}^ Island was taken on 

 July 14. 



123. Sitta canadensis. Red-breasted nuthatch. — Michigan: 

 Common migrant and summer resident, breeding north of latitude 

 44°. 



A rather common migrant in the sand region, at least on Sand 

 Point. The species became common alx)ut August 15, after which 

 date it was seen almost daily with flocks of warblers and chickadees. 

 It seemed to prefer to feed in the jack pines, where the}" were seen 

 climbing up and down over the branches and cones, and even hang- 

 ing, back down, like the chickadees. A number could be seen with 

 nearly ever}* flock of Cape ]\Iay warblers, feeding with them and fol- 

 lowing them from tree to tree. Only two were seen at Rush Lake, 

 August 25, and these were with a flock of chickadees.

 gan: Common resident, breeding all over the state. 



Common throughout the sand region and on Ston}' Island. The 

 chickadee was not rare as a breeder in the sand region and was quite 

 common during migration. It nested in ca\'ities in dead trees, 

 generall\' near the edge of the wooded swamps. On July 3, the first 

 juvenile birds were seen (on Sand Point), and from about August 

 5 it was seen daily in company with the flocks of warblers that fed 

 all over the Point; no large flock of any species of the latter being 

 without a few chickadees. During August it was very common in 

 both the sand region and clay country about Rush Lake. 



125. Polioptila caerulea. Blue-gray gnatcatcher. — Michigan: 

 Common summer resident, breeding all over the state except in ex- 

 treme northern portion and Isle Royale. 



This species was a rare breeder and only observed on Sand Point. 

 A pair was seen on Jul}' 1, and the next day a juvenile bird was noted. 

 It was also seen on July 24 and 30, but not after the latter date. 

 This species is said to be characteristic of the Carolinian zone, but in
