We assembled a team with a range of experience at RSPB Exminster Marshes, in slightly breezy, but overcast conditions for an evening wader mist net catch. Following a dry February, the pools were not as full as previously, there was plenty of shallow water to attract birds pushed off the estuary by the rising tide. We set 9 full-height wader nets across the main pool and 6 large mesh three-panel nets along the bunds, retiring to the ringing base as the sun set.

As darkness fell the breeze dropped, but the clouds cleared to reveal a small but surprisingly bright crescent moon, so initial expectations were not great as some of the team retired to a local hostelry for food. However we deployed the mixed wader call players and soon started catching Black-tailed Godwits. This turned out to be the commonest species of the evening with 24 being ringed. Some showed signs of moulting into their brick-red summer plumage and one bird was very well advanced. We also managed to catch 19 Redshank and a small sample of 8 Duniln, which were colour-ringed as part of our ongoing study.

With a mixed experience team the catch rate was sufficiently controlled to allow the less experienced to develop their skills in handling, ringing, measuring and ageing waders.

An efficient take-down was followed a clean-up of equipment we were packed and away by 12:30 after a very worthwhile and rewarding evening.

Thanks are due to RSPB for granting access to their site for this work and for their assistance and support..

 

Mist-netting Background

The use of mist-nets on high tides during the hours of darkness is less selective in which species are caught, but this technique provides us with  additional opportunities to catch and ring waders in the region. A mist-net catch can usually be managed with a smaller team and without the need for a specialist cannon net license holder or the preparatory work needed to reconnaisace precise roost sites and set cannon nets in advance of the planned catch tide.

Our focus on the Exe estuary is the wintering Oystercatcher population and this species is our primary target for mist-netting as we aim to catch birds flying into the high-tide roosts.

Oystercatchers are faithful to wintering sites so the birds you have seen here years ago may be the same ones now. The oldest Dawlish Warren Oystercatcher on record is at least 36 years old, last seen in Jan 2018.

If you see a bird with one of our colour rings, please use the form on this website to send us the details (ring-code, date, location, species) or you can send email to This email address is being protected from spambots. You need JavaScript enabled to view it..
