Re: [cayugabirds-l] Red-headed Wo caching food

2013-08-22 Thread John Confer 
I have seen Red-headed Woodpeckers caching acorns. At at least one 
location, they cached food somewhat as I have seen in videos of Acorn 
Woodpeckers, putting them in shallow, tiny holes in the surface of the 
tree trunk. This was at Presquille in fall probably a couple decades 
ago. so you might wonder about the accuracy of the memory. It was a 
pretty striking occasion with several birds flying over a parking lot to 
and from the acorn source to the storage trees, so I'm pretty sure that 
is what they were doing.

Cheers,

John

Is there any chance that the fruits are virginia creeper and not wild grape?

Re: [cayugabirds-l] Red-headed Wo caching food

2013-08-24 Thread Dave Nutter 
I don't know what was in the photo or what else the Red-headed Woodpeckers have been eating, but this afternoon at South Mays Point Road I watched one in a tree just next to the road, eating wild grapes. It then flew to one of the dead trees, but not the tree with the cavity I believe they have been using. Both adults were present in the dead trees, but I did not see them approach that tree during the 20 minutes we were there, although someone else reported on eBird today seeing one of them apparently feeding an unseen nestling.--Dave NutterOn Aug 24, 2013, at 10:40 PM, martin borko  wrote:Is there any chance that the fruits are virginia creeper and not wild grape?MartyOn Aug 22, 2013, at 10:48 AM, John Confer wrote:I have seen Red-headed Woodpeckers caching acorns.
