Prothonotary?

[DAVID A LEATHERMAN]

I assume several people have probably checked on the Prothonotary Warbler at Centennial Park since the cold snap hit.  And I assume since there have been no reports, the bird disappeared.  Are these good assumptions?  Negative data is better than no data.  But if buckthorn berries got that bird thru the deep freeze, that would be very interesting news, indeed.  Thank for any feedback, public or private on this situation.

Dave and all,

 

I am leading the Bow Mar/Marston CBC Sat.  Mary Cay and I checked our hotspots Wed including Centennial Pond and the exact spot the PRWA was seen before.  We walked all along that path in the brushy area.  Had an imm BCNHeron on that northeast back trail of Centennial Pond near the PRWA spot--3rd time in 4 CBCs we have had one at Centennial Pond.  I got a photo of it and the adult BAEA at the pond.  A Song Sparrow and White-crowned Sparrow were hanging out right below the PRWA site.  Still a few buckthorn berries.  There was a little open water in the creek below that spot.  The pond was all frozen except a tiny hole with a few usual ducks; a few ring-billeds.  We will have 10-12 people in our group so we will scour the area and hope.

 

Marston was 2/3 frozen so not much there.  Small open spot at the S end, slightly larger open spot at the N end.  Did find a Red-necked Grebe right next to the shore ice on the E side, but no loons spotted and few waterfowl.  We have permission (with prior security checks) to go inside the fence and drive around the entire reservoir only on Sat.  We can see far better inside the fence.

 

Hoping for a little ice melt by Sat.

 

I wonder what numbers of birds others are getting at their feeders.  I have the fewest birds in Nov/Dec since I moved down here from Evergreen 5.5 yrs ago.  Only had 2 subsp of junco during the cold week.  Wondering if the populations are down, birds were killed by the sudden early bitter cold they aren’t used to on the front range, or they haven’t arrived yet from the north or the mts?  My most faithful birds were a local pair of flickers chowing down on suet constantly.  I have twice photographed an adult Sharp-shinned Hawk sitting, resting, hunting in my hawthorn by my patio!  So, maybe the word is out to stay away from my feeders!
