One Oak trees worth of acorns gone underground this month

The first frost overnight. For various reasons I had put the moth trap out again  but deep down I knew it would be a waste of time, which it was - zero moths of zero species. The cold did not put off the local Tawny Owls that were very vocal last night, and the one that came and perched on next door's roof to call,  woke us up several times during the night.

Around lunchtime 3 Skylark flew west over the house as did 7 Redwing. At least three Jay were in South Burn Woods, on their acorn scavenger hunt they do at this time of year. I stood and watched one of them burying an acorn in some soft earth, banging it into the ground quite heavily with its bill.  I remember reading somewhere that a Jay can  carry nine acorns  in its crop and one in its beak and as it stores the ones it cannot eat, it can bury 3,000 in a month. A fully mature oak tree like the ones around here can produce up to 9,000 acorns so these 3 Jays will bury a whole trees worth of acorns this month. Also a small party or tribe of 8 Long-tailed Tit, 3 Bullfinch and 5 Siskin were feeding in the woods.
