Optical equipment: 

N/A. Bird in hand

Distance to bird(s): 

In hand

Duration of observation:

Approximately 10 minutes.





Rural sub-division.  Large yard, mostly wooded in back where feeder and bird was located.  Understory was sparse, but trees were fairly dense. 


Behavior of bird: 

Upon entering yard, bird became very vocal and curious of our activities.  Approached feeder area as trap was being installed, and was resting/perched in sight for approximately 5 minutes before entering trap.




A bird of this age/sex was not to be confused with any other N. American hummer.   Its large size, distinctly different voice, reddish base of lower mandible, blue gorget, and broad blue-black tail led to an easy identification. Measurements/notes taken in field: 

                 Wing:  50.35 mm

                 Tail:  31

       Exposed culmen:  21.23

               Gorget:  ~80-90% complete, but didn't appear as  uniform as that of an adult male.

        Bill grooving: present on ~70% of bill, indicative of imm.

               weight: 4.01 g


grayish belly distinctive of immature male as were the blackish/blue central rectrices with dusky-gray tips. Back primarily green, not contrasting with crown or nape. Notable small, white post-ocular spot present


(photographs submitted with report)                  


Distinct, persistent, loud "chattering" call.  Seemed to be somewhat higher pitched than the call of Buff-bellied hummingbird.


Similar species:

Adult and imm. male Broad-billeds very distinctive, however some references (Howell, 2003) mention the possibility of confusion with Blue-throated hummingbird.  Based on size, color (of body, gorget, tail), and lack of white tips in rects, there was no confusion as to this bird's identity.


Photographs or tape recordings obtained?

Photographs taken by both Myers and Bell.  Myers' photos submitted with report.

Previous experience: 

No previous banding experience with species.  Have seen species in wild in s.e. Arizona.

Notes made from memory


Are you positive of your identification? If not, explain: 


Yes.  This is a distinctive species.  Immature and adult males, in particular, would be difficult to confuse with any other species of N. American hummingbird.
