Back in March 2021 fredford noted that there were Jackdaws associating with Rooks at a local rookery. I have read that in Autumn Rooks perform a display called Stooping when they climb to great heights on thermals and then plunge vertically, obviously pulling out of the dive before they would hit the ground. They are accompanied on their ascent by Jackdaws that do not stoop but presumably go up just for kicks.
Birtle . Twenty-three nests in original place , started in 2013 , eighteen in the one four hundred yards to the east which was establihed one year later and this year there is an additional site between the two , with ten nests . Is this one rookery or three ?
Birtle . 23 nests , they have been busy . The annexe , quarter of a mile to the north east , has about seven nests. Most interesting and amusing to watch the rooks swinging on twigs to break them off . The former magpie nest has been requisitioned . There are always a good number of jackdaws with the rooks . Why is this ? Do they nest amongst the rooks ?
Not sure how many nests make a rookery but there are at least three nests at Asda, Ashton under Lyne, the birds are using the very tall lights that illuminate the main car park. Also a further nest in the trees on the edge of the car park near the by pass. These birds were nesting there last year.
I live over the border in West Yorkshire and the rooks are behind Manchester in returning and rebuilding their nests. Rastrick rookery down from 47 to one (last year) in ten years. The last pair visited yesterday (female has deformed foot so easy to recognise). Rookeries in Ripponden, Greetland and others locally have reduced significantly over past 10-15 years. Mind you, when I lived in Prestwich, I can remember large rookeries in Whitefield, Heywood, Middleton and Heaton Park but they're either long gone or much reduced also. Very unlikely that the trend will change. Birch is the only one which has appeared in the meantime in that area. Jackdaws have increased substantially though around Manchester in the meantime.
There are seven nests in Tyldesley Cemetery this year, without having had opportunity for a full look at the site. Those nests are in a different part of the site to where I recall them being previously. Others in Tyldesley are a single Rook nest at Manchester Road/Cherington Drive opposite the Gatehouse pub and two nests at Kings Court opposite Aldi. I dont know whether either of these latter two sites has been used by Rooks before this year.

Over the past seven days there has been early activity at the above Rookery, the birds only return here to nest, 24 in the tree tops basically in pairs and some tidying up wind blown nests.
Twentynine active nests with a possible 4/5 more, lots of movement and stealing of twigs from nests, at least Fortyfive adult birds present at 1600 hrs today.
Birtle rookery has 24 nests and the annexe,300 yards to the east ,has approximately 16. This is the fifth year and going strong, I am pleased to report. .
Only 19 nests counted at the small wood north of Brookheys covert (Carrington Moss). Although I have not counted the nests here in the past this seems like a reduction on previous years.
