Details surrounding the initial
sighting of this bird are found here. The purpose of
this particular page is to compare molt progression over time. The bird was
initially captured and identified on 8 November 2004. It was recaptured and
photographed on 5 December 2004, and lastly on 25 January 2005. At the time of
the last capture, the homeowner reported that the bird had been behaving
strangely, flying around differently, and acting restless. We expected him to
depart soon, and he did -- last observed 26 January 2005. Also, at the time of
this last capture, we noticed that his tongue was not retracting fully (photo at right) -- something that the homeowner
had observed a couple weeks earlier. The bird appeared healthy,
nonetheless. We have no idea what may have caused this situation and would
appreciate insights from those who may know...
The photos below compare head molt progression during each of these capture events. No molt of the primaries or remiges were noted (they were already adult plumaged). It appears that not much changed between 8 November and 5 December, but an explosion of gorget molt was observed by 25 January!
