BIRDS OF MINNESOTA. 275 



nest to lay five eggs, she would try her bill and feet at building 

 a nest for herself exclusively. 



These birds distribute themselves over the entire State, so 

 that they may be seen almost daily in their favorite localities 

 until late in the autumn as already mentioned, but at no time 

 in such vast numbers as Coues has described them in some of 

 the other western states. Their remarkable disappearance in 

 August which he speaks of (in his "Birds of the Northwest,") has 

 never occurred here to my knowledge, although I have noticed 

 that they were less active during the period of their moulting. 

 Mr. Washburn found them common in his explorations of the 

 ornithology of the Red river valley in the middle of August, 

 and in Otter Tail county on the 17th of October. 



My memorandum says for one year, "Very common Novem- 

 ber 15th in the middle and western part of Hennepin county."

YELLOW-HEADED BLACKBIRD. 



Whatever their numbers in other western localities, the Yel- 

 low-headed Blackbirds are far from abundant in any portion 

 of Minnesota yet explored. 



Neither are they even approximately uniformly distributed, 

 although all of the conditions favorable for them are found in 

 nearly every considerable portion of the State. 



The males are so large and their markings so conspicuous 

 that they cannot escape attention even when their numbers are 

 very few, and they confine themselves so closely to their breed- 

 ing places that whoever finds them once is pretty sure of find- 

 ing them at the same places the next time he seeks them.
