As a participant in Project Feeder Watch, I know you are interested in disease in feeder birds so I am submitting a photo that shows a house finch with an abnormal beak.

Dear Katherine Young. from Boulder.. I, am but. a grateful observer, of the wonderful birdfeederwatch.. and your picture is,, highly different, .. I, would suggest that even though the subject is of a sensitive matter that,, perhaps you may wish to report this,, as .. and as you have probably done so..
Every observation,, is important.. and unusual cases. may provide very important information..
issues.. which may or may not be explained , observed and or.. .. your feedback is always important.. and, as a bird feeder.. my observations have always..had a careful and immediate investigation with the proper designation authorities.. never underestimate.. your observations.. they will be.. with highly noted ornithologists.. be viewed.. I, strongly suggest..
Always submit.. a sick bird report..and ask to submit to sick bird report your perception of such an occurance..
ad,tr.qc.. a fellow bird feeder watcher. and not an expert in these matters..
I have two male HOFI at my feeder with deformed beaks (in southern Arizona). One is a very yellow color morph and the other is an orange color morph (as opposed to the more common red morphs). The beaks are both very elongated on the lower mandible and truncated and twisted on the upper part. Both are feeding and look healthy otherwise. I have poor pictures available. I wonder if this is evidence of avian keratin disorder or possibly a developmental abnormality.
