elder tree about 300 yards over a low 

 ridge into another canyon. Here they 

 built a bulky nest some fifteen feet up, 

 from wh'ch on the 8th day of June I 

 took five eggs, incubation very slight, 

 minute bloody traces being visfble in 

 the yolk snd white of the eggs. 



This last, it will be remembered, was 

 their eighth set. Now for their ninth 

 set they changed the entrance of their 

 nest which had held the seventh set 

 to another side and relined the nest. 

 On the 18th of June I took from this 

 nest a complete set of four eggs. 



Where they then went I do not know, 

 but there is a pair at present nesting on 

 this hill. They have raised one brood 

 already and a day or two ago presented 

 me with a fine set of five fresh eggs. 



Here then were nearly twenty nests 

 built and forty-one eggs laid in the 

 short period between March 9 and June 

 18— or three months and nine days, 

 something over one hundred days. 



The eggs seem to be quite uniform 

 both in size and manner of markings. 

 The intensity of color, however, shows 

 a gradual decrease from deep salmon 

 red to a very weak pink. I have no- 

 ticed, however, in a series of Pacific 

 Horned Owl eggs taken from one pair 

 of birds this year and consisting so far 

 (they are still laying) of one set of five, 

 two sets of three and one set of two. 

 that there is a perceptible decrease in 



size of the eggs.

Birds Observed within the Corpora- 

 tion of Kalamazoo, Mich. 



The corporation is at present two and 

 three-q'iarters by three miles in size, 

 but in past years was smaller. There 

 are many changes and many species 

 once abundant within our boundaries 

 are now seldom or never seen. These 

 observations extend over a period of 

 more than thirty years. 



The species found breeding within 

 the corporation are marked with a *.
