I rare visitor in Minnesota and was not 

 the month of April, 1892, several 

 pairs -were observed near St. Paul for the first time. In June a nest 

 was found by a local collector and brought to me for identification. The 

 parent being taken with the nest it was easily identified. This find set 

 me to searching for their nests the next season, and I was rewarded 

 with a fine set of five eggs which were taken with the nest i 

 in June. That was the only nest observed in 1893. The past f 

 the birds were much commoner than ever before, and four nests were 

 found, three with eggs. The first nest was taken May 27, and contained 

 four fresh eggs. The second set was taken on June 2, with five slightly 

 incubated eggs. The third, also taken on June 2, contained four fresh 

 eggs. The fourth nest, taken on June 18, contained four young, just 

 hatched, and one addled egg. This is, I believe, the first record of the 

 Gnatcatcher breeding north of 43° N. lat., St. Paul being in lat. 45° N. 

 All the nests, with one exception, were taken in West St. Paul, in 

 Dakota County. They were all placed on horizontal branches of the 

 burr oak and the height varied from twelve to twenty-four feet.—

I have also observed that 

 when the Blue-gray Gnatcatcliers {PolioptUa 

 cwrulea) are building and a storm partly de- 

 stroys their nest, they will tear down the old 

 structure and rebuild it again in another tree, 

 using the same material for tlie now nest.
