You might have to start putting up more feeders and charging $5 per visit if your unusual hummingbird visitors keep coming.Unknownhttps://www.blogger.com/profile/05983038626350968191noreply@blogger.comtag:blogger.com,1999:blog-2578555892697401095.post-31894693960848437042009-11-25T08:14:07.023-08:002009-11-25T08:14:07.023-08:00I actually considered that, Philip.

It's missing a prominent lower frequency found in RTHU and BCHU that starts around 3000 Hz.Birdernaturalisthttps://www.blogger.com/profile/04839261136397086450noreply@blogger.comtag:blogger.com,1999:blog-2578555892697401095.post-67429843725128541482009-11-24T11:52:13.218-08:002009-11-24T11:52:13.218-08:00Hi Rich:

The photos are suggestive that it has a pretty green crown and the profile of the sonogram looks similar, although the call maybe slightly lower in pitch (or higher, whichever corresponds to lower magnitude in KHz). Perhaps the sonogram is a male call and the female's call is similar but on a slightly different pitch?Philip Klinenoreply@blogger.comtag:blogger.com,1999:blog-2578555892697401095.post-49766421256226226112009-11-23T15:26:12.391-08:002009-11-23T15:26:12.391-08:00Rich, I think your sound files provide evidence th...Rich, I think your sound files provide evidence that the bird might be Black-chinned x Costa's. I've discussed why I think so on <a href="http://earbirding.com/blog/archives/1161" rel="nofollow">my blog</a>. I recommend getting someone to capture the bird, and I recommend getting more sound recordings if you're able!Nathan Pieplowhttp://earbirding.com/blognoreply@blogger.com
