(this is a bird by the way, with a brain the Boreh Olam created, be careful next time you refer to someone as a birdbrain)
Clark’s nutcracker (Nucifraga columbiana) stores 22,000 to 33,000 nuts of the whitebark pine in up to 2700 locations over an area of over 100 square miles, and REMEMBERS where almost 70% of them were placed.(it may be that it remembers ALL of the locations,but some landmarks may have moved)
let me repeat that:
22,000 to 33,000 nuts in 2700 locations over an area of over 100 square miles, and REMEMBERS!
The seeds are usually buried in a hole in the ground that the jay digs just before depositing the seeds. One to ten seeds are placed in the hole and the caches are scattered over a large area.
The hole is covered over and then a leaf, stone, twig, or scrap of litter is placed over the hole to camouflage it. The bird flies away and will not return to the hole until it is ready to retrieve the seeds.
How Birds Remember Cache Locations
Multiple experiments performed with captive birds in Russell Balda’s lab at Northern Arizona University have demonstrated they can remember caching locations by noting the positions of stones, shrubs, and other landmarks in the area.
In the wild, nutcrackers will fly directly to a cache location even if the ground, trees, and shrubs are covered with several feet of snow, dig down to the precise location of the seeds, and retrieve them.January 28, 2009 7:23 pm at 7:23 pm #1097610RoshYeshivahMember
Another one of feivel’s wacky threads. What does the bird need all that seeds for does he eat them all?January 28, 2009 7:23 pm at 7:23 pm #1097611moish01Member

Seems like there are many Clark’s Nutcrackers in the NY Metropolitan area given the large distribution of nuts in said area…………January 28, 2009 7:30 pm at 7:30 pm #1097615oomisParticipant
Moish, how do you DO this??????? Amazing and really beautiful.January 28, 2009 7:34 pm at 7:34 pm #1097616moish01Member

Hey Itzik, are you a Citidiot?January 28, 2009 7:44 pm at 7:44 pm #1097618
what you say makes sense
unfortunately you will have to find a different explanation
clarks nutcrackers are only found in the western parts of north americaJanuary 28, 2009 8:09 pm at 8:09 pm #1097619SJSinNYCMember
Feivel, another area with a lot of nuts 🙂January 28, 2009 8:23 pm at 8:23 pm #1097620Itzik_sMember
Mayan_Dvash, yes I am a former Citidiot if you mean a former customer of Citibank as well as if you mean a former resident of NYC!
Feivel – I just read that the first Clark’s Nutcracker was bred by Napoleon Atilla George Washington Clark, a resident of Pilgrim State, as a way to distribute the nut population which surrounded him.January 29, 2009 1:59 am at 1:59 am #1097621asdfghjklParticipant
