Family ABDEIDiE : The Herons. 



*171. Ardea herodias, Linn. — Great Blue Heron. 

 An abundant constant resident. 



*172. Herodias alba, [3. egretta, (Gm.). — American Egret. 



This species was hrst noticed at Stockton, in the spring of 1878, on 

 the 1st day of April. It is common in summer, and my impression is 

 that it is a constant resident, as it remained here this year up to the 5th 

 of December.* On the 7th of December, 1878, I saw a flock of forty 

 or fifty at Stockton.

*173. Garzetta candidissima, (Gm.). — Lesser Egret. 



The first of this species observed after March 6, 1878, was a flock of 

 seven or eight on May 21. It was rarely seen after October 4, and I sup- 

 posed it had gone, but on the 20th of November I saw a flock of nearly 

 a hundred. I have not noticed it since that time, though it may have 

 gone to the centre of the tule swamps. It is an abundant summer resi- 

 dent at Stockton.

*174. Butorides virescens, (Linn.). — Green Heron. 



The Green Heron is an abundant summer resident of the valleys. It 

 was first seen at Stockton April 15, 1878, and disappeared in the first 

 week of October. 



Many built their nests in the willows by the San Joaquin Elver. I 

 examined three nests. In one of them were six eggs; in the other two, 

 four eggs each.
