Results of 2010 Maidenhead Bird Survey in Detail

MWRG Breeding bird survey of central Maidenhead waterways

Due attention was given to parameters which may affect the activity of birds i.e. period in the year, time of day and weather conditions. Timings of the visits were made to give an accurate assessment of the bird populations present within the Site, and also to determine which species were using the Site to breed, and which were exhibiting territorial behaviour.  Birds that had bred successfully and were with young within the Site were also noted.  Species which were unlikely to be breeding in the area but were using the site to roost or provide feeding opportunities were also recorded.

Four survey visits were conducted between 21 April 2010 and 15 June 2010.

A summary of the breeding birds with a recognised conservation status (e.g. Schedule 1 species, BAP species (UK and local) and red and amber listed birds of conservation concern) found within the Site:

  • Common kingfisher (Schedule 1/Amber) – No breeding pairs found but a single adult bird was observed fishing to the south of the Site on 4 May 2010, before flying south.
  • Grey wagtail (Amber) –Two breeding pairs were located feeding young in the nest on the site; one situated near to the Chapel Arches culvert, the other beneath the Green Lane Bridge
  • Dunnock (Amber/BAP) – Thirteen pairs were found breeding whereever suitable hedgerows or bramble scrub were present on the site
  • Song thrush (Red/BAP) – Four or five pairs were found located in trees, scrub or gardens within the survey area
  • Common whitethroat (Amber) – One pair was located breeding
  • Common mallard (Amber) – Two breeding pairs
  • Common starling (Red/BAP)  – Two breeding pairs observed breeding within the Site

As revealed on the maps, this area at the north end of the 'ring' is the bird hotspot.  Dunnock, mallard, green woodpecker, song thrush and whitethroat were all recorded here.  In the foreground is Moor Cut, currently dry but to be refilled as part of the scheme.  Beyond is Town Moor.   Looking north-west from 51°31'33.72"N   0°42'54.20"W
