Rookery survey progress

This map shows the progress we are making in Pembrokeshire with the all Wales Rookery Survey 2022-23.

For a list of known rookeries (from previous surveys) see here

Results to 30th April 2022

This map will be updated every few days, so please enter your records (positive or negative) as soon as possible.

Hatched square = priority tetrad, no rookeries found

Grey square = priority tetrad, rookeries found

Red dots = Rookeries counted

Black dots = Rookeries checked but nothing there now.

Please enter your records (even if it is a zero count at a previously known site). If you enter a zero count, don’t forget to click on the button that asks if it is a negative record. I see that some sites on the map are showing as a counted rookery (in red) when actually there was nothing there – but the negative record button wasn’t used.

Records can be edited later if you do a recount and find more nests there – if you counted a rookery in March or early April, it may be worth having another look now – before there are too many leaves on the trees.

Download Instructions for entering records here.

Finding tetrads in a 10km square

Casual records can be entered using a GPS reference or picking the place on the map/aerial photo. You can do a more intensive search by tetrad 2km x 2km square. Here is how to find a tetrad:

A 10km square is normally divided into 100 1km squares, Some surveys, such as this one, is based on tetrads – 2km x 2km squares. Within each 10km square, the tetrads are given a letter as shown in figure 3.

Lapwing – breeding records since 2000

Vanellus vanellus – CORNCHWIGLEN – Breeding resident and winter visitor

The lapwing has declined drastically as a breeding species in Pembrokeshire. See the 2003-07 breeding bird atlas. The article charts the decline since 2000.

2000 – 4 or 5 pairs attempted to breed in Castle Martin area; Skokholm 2 nests with incubating birds and Skomer 1 pair – no success reported.  On Ramsey 7 pairs raised 4 chicks.

2001 – Only breeding record received: Ramsey, 10 males holding territories, 8 clutches laid, 5 possibly 6 fledglings. No breeding birds on Skokholm for just the second time on record; on Skomer an adult appeared with a fully-fledged juvenile on 4 July. As a breeder seems to be in a perilous state.

2002 – Only breeding records received: Ramsey: 9 males holding territory. 8 clutches laid; 8 young fledged, including 3 from the second clutch.  2 adults + 2 chicks at Freshwater W 26 May. Possible incubating at Brownslade 1 June. 5 of 6 chicks, from 2 pairs, ringed at Kilpaison 17 May.

2003 – Lapwings maintained their tenuous hold in the county.  8 males held territory Ramsey, 6 young fledged; up to 6 pairs at Kilpaison, but no chicks fledged.

2004  – Breeding attempted at Castlemartin Corse.  On Ramsey there were 8 apparently occupied sites, 4-5 young fledged.  4 pairs bred at Kilpaison.

2005 – Ramsey – 5 pairs, 5 young fledged, 5 or 6 nests at old BP site, Kilpaison, 7 pulli ringed.

2006 – Ramsey – 6 pairs fledged 8 young. Also 2 pairs + 2 singles at old BP site, Kilpaison and 1 pair Range E, Castlemartin in April/May.

2007 – Six pairs attempted to breed on Ramsey but no young were fledged

2008 – no records of breeding

2009 – A pair at Treswny Moor from 3rd May to 4th June showed behaviour suggestive of breeding, but breeding not confirmed. 5 pairs bred on Ramsey but the young were predated, chiefly by corvids, and no young fledged. 5 pairs attempted to breed at Kilpaison, again all were unsuccessful

2010 – Two pairs bred on Ramsey

2011 – The only report of breeding came from Ramsey, where two pairs fledged just two young in total.

2012 – Three pairs bred on Ramsey but only one young fledged. Otherwise there were no reports of breeding and the only summer record was of a single bird at Marloes Mere on 8th July.

2013 – A report of presumed breeding involved two adults and three juveniles at Marloes Mere on 1st Sept, and at least one pair is also believed to have bred at Castlemartin Corse but no details were submitted. One pair bred on Ramsey.

2014 – no reports of breeding on the mainland – one pair bred on Ramsey, fledging one young.

2015 – no breeding records received (two males on Ramsey but no females).

2016 – Breeding attempted at Castlemartin Corse, but outcome unknown.

2017 – No reported evidence of breeding

2018 – No breeding records received.

2019 – No breeding evidence was reported.

2020 – No breeding evidence was reported

A list of known rookeries in Pembrokeshire

These tables are to help you find rookeries to count for the 2022-23 survey.

For this survey, you can register to do a full survey of priority tetrads, and/or submit casual records of rookeries from anywhere.

If you visit any of the sites listed in the tables below, and do not find any rooks nesting, please still enter the data as a zero count, so that we know it has been checked. There are likely to be plenty of rookeries that we do not know about, and some rookeries that will move to a new group of trees.

These tables have been compiled from various sources including bird reports, breeding bird atlas data, detailed local studies, BirdTrack, etc. There was no standardised method of data collection for historical records, so it is impossible to eliminate all inconsistencies.

Where a count is given in the tables below, it is the highest count of nests in that decade.

A zero count means there were definitely no nests seen (although we don’t necessarily know exactly when the last occupation was). Note that in 1996 there was a national survey in which random tetrads were surveyed, some of which had zero counts but no known earlier records. A blank means there is no data – probably because the site wasn’t recorded in that decade.

Where there is a named rookery in a tetrad, that does not mean it is the only rookery there. Where the tetrad reference appears in the place name column, that is the only information available.

The same rookery may have been given different names by different observers.

Where a particular named rookery appears in more than one tetrad, it may be that:

  • it is located on the border
  • the rooks have moved across the border to a different clump of trees
  • the nests are sufficiently spread out that it really does cross the border (the rooks aren’t reading the maps first!)
  • the surveyor estimated the grid reference incorrectly (especially in the days before GPS and aerial photos)
  • different surveyors estimated the grid refs differently
  • For some sites, we have only a place name, and the grid reference from that
  • The nearest place name is not necessarily in the same tetrad as the rookery
  • A detailed local survey (eg at St Davids) may divide a single rookery into smaller pockets of activity

Do not worry about these inconsistencies. These tables are purely to help you find rookeries to count for the present survey. We may be able to iron out a few more of these inconsistencies in the future.

We can provide extra details about tetrads with named rookeries – email here – giving the tetrad name or the 10km sq, or your postcode, so we know what area you are interested in.

Please enter your records (even if it is a zero count at a previous site)

Barn Owl – movements

Tyto alba – TYLLUAN WEN – Breeding resident.

Breeding adult barn owls in Britain are largely sedentary. Young barn owls do not disperse very far, with a median dispersal distance of 12 km from the nest, while only about 4% of movements are over 100km. In mainland Europe, dispersal distances are greater, often more than 50km with over 10% going more than 100km. Most recoveries in Wales have been less than 20km from their ringing site, but there are some exceptions.

2007 – A bird ringed at a nest at Glenurquhart, Highland, in June 2007 was hit by a car 624km away at St Ishmael’s that December.

2021 – At the end of October, Richard Crossen found a dead barn owl at Castlemartin Corse.  It had been ringed as a nestling in June 2021 at a site in the Towi valley, and so had moved 70km to coastal west

2021 – On November 7th, Andy Jones found the fresh remains of another barn owl on a farm just east of Lamphey.  There wasn’t much of the bird left – only the legs – suggesting it had been predated.  This one had been ringed as a nestling by the Mid-Wales Ringing Group at a site south-east of Machynlleth, 125km away!
