Winter Visitor and passage migrant

Site And Records Information

Hen Harrier bred in the harbour in 1875 and possibly in 1922 where Dr K B Rooke wrote in 1948 – “the Hen Harrier winters from the Wareham Channel to Little Sea… fewer records from northern heaths ….where it’s a scarce winter visitor. Probably suffers heavily in these areas at the hands of keepers, farmers and others”

The first roost was found “in tall heather at Arne in 1972 and continued until 1977, when a period of prolonged snow flattened the site causing the area to abandoned.” Tasie Russell.

In a survey conducted by Tasie Russell which included analysis of twenty years of sightings from 1968 -1988, 78% of sightings of Dorset’s Hen Harriers were in Poole harbour where 5% of national wintering birds occurred here with a harbour maximum of 8 in the winter of 1985.                              During that survey 8 different roost sites were found in the harbour.

Numbers have declined since the late 1980s when individual winter roosts of up to six birds were recorded with a harbour maximum of eight were recorded during one co-ordinated roost count. In more recent years regular surveying rarely shows more than four birds present at any one time although six were briefly in the harbour during February 2014 and 7 were present in Feb 2018.
The use of roost sites has to remain confidential but remains unpredictable with frequent changes in numbers, groupings and locations.
Birds can most reliably be seen by day either from the Middlebere hide, at Arne RSPB or at west harbour locations such as Lytchett Bay and Swineham. Less frequently, they may be seen on Godlingston Heath, around Rempstone and ‘just outside the harbour’ area over the wet bogs of Wareham Forest.
A juvenile male that wintered in 2013-14 had been ringed and originated from Argyllshire. Other local recoveries have involved birds from nests in Cornwall, Lancashire and Aberdeenshire.
A second calendar year male that had remained from the winter cohort was seen to display above Swineham in mid-April 2016 and in August 2018 a fresh juvenile male spent a week around Swineham and Keysworth which is an exceptionally early date and possibly suggesting it fledged somewhere in southern England.
Winter 2022/23 was a good winter with 7 different individuals using the harbour either to hunt, roost, or both!

Resident

Site And Records Information

The last 50 years has seen a huge decline in breeding numbers where it was said that Brownsea Island used to host 400-600 nests in the 1960’s, then compare that to only three nests in 1980. In 2016 a breeding gull survey was conducted showing that a population of 811 pairs now breed within our Poole Harbour recording area. Still easy to see in most places around the harbour, with Poole Quay being a good place to look as they hunt down free chips! Despite the breeding problems the non-breeding numbers are still strong with 2000- 3000 in the harbour at peak times. Also recorded in Poole Harbour is the sub-species Scandinavian Herring Gull

Summer Visitor & Passage Migrant

Site And Records Information

In spring Hobby are typically very active and relatively easy to see as they gather over heathland, conifer plantations and bog sites within the harbour after migration from wintering areas in sub-Saharan Africa. Large feeding groups of up to 12 have been recorded on the south side of Wareham Channel during mid-May though smaller groups can appear almost anywhere. The birds that then remain in the area to breed become less conspicuous during the nesting cycle when individuals are best seen around the Arne RSPB heaths, Middlebere, Slepe Heath and Hartland Moor, although fledging success varies according to the availability of large insect prey. During most years there is also a presence to the north of the harbour at both Swineham gravel pits and Lytchett Bay. The wet bog surroundings of nearby Wareham Forest are just outside the harbour boundary but routinely hold hunting birds with nesting within the forest boundaries recorded annually.

The earliest record is 27th March 1994 at Godlingston Heath and the latest is 20th Nov 2010 at Hartland Moor.

Breeding totals for the harbour are estimated to be between 3-6 pairs.

Scarce Passage Migrant

Site And Records Information

Could potentially pass over anywhere on migration. Seems to have become scarcer in recent years. Year 2000 saw a record influx into Britain at the end of September involving at least 500 birds and Dorset enjoyed between 143 and 159 sightings involving a min of 77 individuals. The harbour recorded 5 of these. There was a further influx in 2008 but the harbour missed out completely.

Rare Visitor

Site And Records Information

Scarce visitor to the harbour, almost annual in recent years. Nationally this species is a scarce migrant. Its occurrence is fairly stable with 10 year means varying from 93 (1990’s) to 147 (1960’s). The current decade mean is 124. There are many historical records from various places around the harbour. Below is a complete list since 1980. Spring records are very much the norm, with only 8 of the following records relating to autumn. There is one winter record from 2013 when a bird spent the winter on a housing estate in Hamworthy!

Summer Visitor & Passage Migrant

Site And Records Information

Sporadic breeding sites around the harbour with the manor house at Upton CP hosting nests. Passage migrants arrive mid April and pass through feeding over the many moors and fields around the harbour and then start to depart early September and all the way through October. Large counts of up to 1000+ are always possible if watching from a good migration vantage point such as Ballard. In mid-summer feeding colonies can be found over Swineham GP nad Lytchett Fields.

Site And Records Information

Many breeding colonies in urban and rural areas around the harbour, but declines are evident in various places such as Brownsea and Ham Common. Can occur as a passage migrant in September and October with Ballard Down and South Haven logging passing birds on migration.
