tioned: Anhinga anhinga, Mycteria amcricana, Florida coerulea, 

 Ionornis martinicus, Scardafclla inca, Catharista urubu, Parabuteo 

 unicinctus harrisi, Buteo abbreviates, Polyborus chcriway, Centurus 

 aurifrons, Pyrocephcdus rubinus mcxicanus, Passerina ciris, Bceolo-

The intrusion of the Upper Sonoran Life Zone results in two 

 interesting developments of the bird life. The first is the remaining 

 here through the summer of several Upper Sonoran species, which 

 here find the extreme southwestern limit of their breeding range: 

 Sayomis phoebe, Passerina cyanea, Lanivireo flavifrons, Mniotilta 

 varia, Dendroica dominica albilora, Oporornis formosus. The second 

 result is the occurrence of several western species that rarely if 

 ever extend further eastward: Callipepla squamata, Cyrtonyx 

 nwntezumoB mearnsi, Otus asio aikeni, Bubo virginianus pallcscens, 

 Coccyzus americanus oeeidmtalis, Melanerpes formicivorus, Tyran- 

 nies verticalis, Aphelocoma texana, Corvus cryptoleucus, Icterus 

 bullocki, Amphispiza bilineata, Aimophila ruficeps eremo?ca, Pipilo 

 fuscus mesoleucus, Passerina amama, Salpinctes obsolctus, Catherpes 

 mcxicanus conspersus. 



The list contains the usual percentage of accidental visitants: 

 Phalacrocorax vigua mexicanus, Dendrocygna autumnalis, Sphyra- 

 picus thyroideus, Tyrannus mclancholicus couchi, Zamclodia melano- 

 cephala, Hespcriphona vespertina, the last of which is a new bird 

 for the State. 



List of Species. 



1. Podilymbus podiceps. Pied-billed Grebe. — Occasional in 

 winter on the Guadaloupe River. One was brought to me on August 29, 

 1910. 



2. Larus franklini. Franklin's Gull. — On April 26, 1909, a 

 severe hail storm passed down Turtle Creek (a tributary of the Guada- 

 loupe) at about 9 p. m. and did much damage, killing some livestock and 

 many small animals and birds. Several Franklin Gulls were picked up 

 dead and one was caught alive by a friend. I had not seen the bird here 

 before, but saw a small flock on May 17, 1910. 



3. Hydrochelidon nigra surinamensis. Black Tern. — A Tern 

 seen nearly every year in late summer and early fall along the Guadaloupe 

 belongs probably to this species; I have never been able to procure a speci- 

 men. Saw one August 23, 1910.
