Farmyard birds

First opportunity to look in here for a while, at my age it’s good to be busy ,
I suppose my original post was an indication of wildlife and bird life in particular interaction with modern farming methods, (I’d be the first to acknowledge that it’s not all good)
I still have Yellowhammers, four singing males this summer..I now leave clumps of gorse through the hedges at the times I get round to hedge cutting, two acres of waste ground has also been left to grow gorse, so there is a fairly stable population the last couple of years.
As indicated in posts above stubble is very important to a wide variety of over wintering birds, the EU says there has to be green cover over winter now but even though they say it’s to encourage wildlife plus preventing nitrates leaching it probably works better at the latter.
I did an experiment for my own interest a couple of years ago, one field that always had overwintering Skylarks and Snipe as well as all the usual finches was left with weeds and grasses that shot up post harvest and another had the straw from the combine chopped and the weed growth was sprayed with a weak herbicide.
The first field had the Skylarks and Snipe as usual plus a few Pheasants and that was it...the second field was alive with all types of birds over the winter, was very pleased to count fourteen Yellowhammers at one stage in a large flock of finches etc.
Unfortunately age and circumstances mean that my full time farming days are over and I won’t have much say in what happens next here but there are a couple of outfarms that I’m getting a lot of satisfaction from improving from a wildlife perspective despite the cynicism of the lads who have them rented!
