BIRDS OF LOWER CALIFORNIA. 311 



Description of the Young Plumage of Geoflitijpis heldingi, in 

 in these Proceedings, pp. '20-22]. 



The birds kept mainly within the bullrushes and bushes 

 of the creek, but could be called out by imitating the cries 

 of a bird in distress. I frequently heard them singing, 

 sometimes in the top of a low tree. Their notes are 

 rather loud and quite clear, an interval of a few seconds 

 occuring between each song. The three songs which I heard 

 sung by the same individual March 31, were noted on the 

 spot. In different places of the song occurred a low. short 

 buzz, represented by stars in the following. The first song 

 occupied about five seconds. 



1. Sweet, sweet ■^- -^ -^ ear ^ ^ ^ siveet, sweet ear ^ ^ ^ 

 siueet, sweet ear. 



2. Sweet, sweet ear -^ -^ -^ siveet, siveet ear. 



3. Sweet, sweet ear -^ -^ - sweet, sweet ear -^ * ^ 



The birds were found on the west coast at lower Purisima 

 canon, and as far north as San Ignacio, consequently they 

 are not nearly as localized as has before been supposed.
