It's been really puzzling about the large quantities of Linnets I have had in recent days whilst doing my vismig counts from Vicarage Lane in Burton. In normal years I guess I would get about 20 Linnets during a daily a count at the very best, although this usually all changes when it gets to the middle of October and then the daily counts can get to four score or even above the 100 mark!
But what is remarkable about this year is that I have been getting regular daily counts over two hundred since about the 16th of September with 5 counts of over 500 plus between the 21st and the 24th of the month, in fact the count had risen to 896 on the 24th and 655 by the 25th.  These extroadinary numbers I must say have had me wondering what is going on! I have mentioned it to others and some have suggested that a local food source may be enticing the birds, another suggestion is that maybe a new roost has formed and that we are getting birds from this.
In my own mind I am now clear that the majority of the birds have without doubt been passing through the area directly on a regular migration line, although I have been suspect about 100 birds which seem to have remained local and can be seen blogging for the past few days.
I have checked all the fields looking for any enticing crops and have managed to find two things which could well be tempting some of the blogging birds to feed up on, although the bulk of the birds are seen to pass directly through our area totally ignoring any food crops or such. The crops which could be of interest to the bloggers are Fat Hen (Chenopodium album) and possibly the 'bolters' within the fodder beet (Beta vulgaris).  I can show photographs below of the crops.  The Fat Hen do look very much like a millett type of food, yet to me look very much unripened at the seed heads, whether this makes a difference or not! (see photos below)
The roosting theory does not uphold having checked out the areas later in the day and nothing is apertaining.
After noting high Linnet numbers at both Long Nab, Burniston, N. Yorks on 12th September 2019 with 434 birds and at Spurn on 26th September 2019 with 759 birds. Having been unclear to what was going on I can now get some sort of comfort knowing that at least other areas have also been getting large numbers of Linnets as well. 
I guess I am still left with the following question.  But why all of a sudden as this happened when its never been recorded previously in the past ten years?

It's now early January 2020 and most of the fodder beet has now been harvested.  I am still witnessing up to 200 flocked Linnets in the local area which corresponds to similar numbers previously recorded during January 2019. This over wintering of Linnets in the area was not recorded prior to the more recent growing of fodder beet and its associates (Fat Hen etc) which has obviously been the attraction for these birds to overwinter here.
