Farlington Marshes; a winter home for migratory geese, ducks & waders; threats to waders. 15.11.21

Updated: Dec 1, 2021

On Monday 16.11.21 I visited Farlington Marshes Nature Reserve (Hampshire and Isle of White Wildlife Trust) for the first time. It is a fabulous reserve, at the the top of Langstone Harbour, between Portsea and Hayling Island


This reserve offers wonderful walks all year round, but during the winter it really comes to life, playing host to a staggering number of migratory, overwintering wildfowl.

Dark bellied brent geese, wigeons, teals, avocets, redshanks and dunlins flock to Farlington Marshes in their thousands, creating unrivalled bird watching opportunities. The winter also sees the return of the ever popular short eared owls, which hunt over the Point Field and southern end of the main marsh.

I reached Farlington from Brighton by train and bus. After alighting at Havant railway station, I took the Stagecoach 21 bus to Portsmouth from the nearby bus station, see: 21 Bus Route & Timetable: Portsmouth - Havant | Stagecoach (stagecoachbus.com). The bus goes every 30 minutes and takes about 40 minutes from Havant; alight at Walton Road, Farlington; then walk south to the reserve (15 minutes walk); you need to cross the roundabout that forms the junction of the A27 and the A2030, but this is easy as their are traffic-light controlled pedestrian crossings.


The journey to Farlington emphasises the urbanised character of the Solent region. The bus from Havant passes though Leigh Park and Bedhampton, both large areas of post-war municipal housing. I got off the bus in Drayton/Farlington, the stop is in an area of retail parks and industrial estates. But in 15 minutes from the bus stop you reach the "wildness" of the Farlington Marshes in Langstone Harbour, which, along with Chichester Harbour. forms one of the largest Ramsar locations in England (5,810.03 hectares). Ramsar sites are wetlands of international importance designated under the Ramsar Convention. See Ramsar Sites | JNCC - Adviser to Government on Nature Conservation for a list of Ramsar sights in the UK. The contrast between the urban/industrial hinterland of Langstone Harbour and its natural beauty in fascinating.


However, the marshes are merely a fragment of the marshes that once surrounded the harbour; and whilst there are many birds; the numbers of waders is declining dramatically; ten years ago the Guardian reported, and the situation has worsened since then


The magical winter wildlife spectacle of hundreds of thousands of wading birds converging on British estuaries could be under threat as research shows big declines in some of the most familiar species.


Results from the Wetland Bird Survey reveals that ringed plovers, oystercatchers, redshank and dunlin are among the eight most abundant species overwintering on UK estuaries to suffer significant and consistent population drops over 10 years.


... Ringed plovers have suffered a decline of 39% in 10 years in over-wintering birds and those breeding in the UK. Redshank have fallen by 26% and Dunlin by 23%.


Curlew have fallen by 17% and oystercatchers by 15% in the 10 years to June 2012. Knot have dropped by 7% and the bar-tailed godwit by 10%. Grey plover are down by 21%, according to the data collected by thousands of volunteers. Wading birds declining in the UK | Birds | The Guardian

The walk to the entry of the reserve from the footpaths crossing the A27/A2020 roundabout.


The first thing I saw after crossing under the A27/A2020 roundabout; two Brent Geese tucking in, right next to the bank of Langstone Harbour.

Brent Geese overwinter in Langstone Harbour in Huge numbers For more information on Brent Geese, see the blog post: Langstone Harbour & Hayling Island: Brent Geese 23.10.21


Brent Geese and the industrial landscape of the north of the Island of Portsea which forms the western shore of Langstone Harbour

The mud flats of Langstone Harbour are similar to those of the Wash; although they are surrounded to the west and north by urban and industrial landscapes. The contrast between the summer and winter worlds of dark-bellied Brent Geese is great. Brent Geese come to Langstone in the winter, surrounded by industry and housing; whereas they spend most of their year in the artic wilderness of northern Siberia.


The Brent Geese eat Eelgrass on the mudflats first; when that is exhausted they move onto grasslands on shore including farmland and grass round towns - playing fields; parks. See: Alarm call | Birds | The Guardian



Brent geese flying over the sea wall into Farlington; possible to the Farlington playing fields; Brent geese forage on green land sights around Langstone and Chichester Harbours e.g. Portsea Island, the south coast of Hampshire and West Sussex, Hayling Island, Thorney Island and the Manhood Peninsular; but mostly when saltmarsh eelgrass is used up.

What I saw: Brent Geese, Canada Geese; Oystercatchers, Black-tailed Godwits; Dunlin; Curlew; Grey Plovers; Avocets; Lapwing; Redshanks; Little Egrets; Teal; Wigeon; Shelducks; Tufted Ducks; Pintails; Mallards; Coots; Moorhens; a Kestrel; Long-Tailed Tits; Linnets; a Thrush, Blackbirds; Magpies; Carrion Crows,


The beginning of the sea wall (west) of the marshes: this weird remains of a building is part of the Portsmouth Starfish project, to protect Portsmouth from bombing in the Second World War.

There were several of these Starfish sites around the country and they were set up as town decoys and in one night raid alone our local Starfish site in the north of Langstone Harbour and along the western coast of Hayling Island drew almost 150 bombers away from the city, causing them to attack nothing other than salt marsh.
