2009

High autumn-passage count

24 Aug – A count of 30 remains (as of July 2020) the highest autumn-passage day-total since publication of The Birds of Lundy in 2007.

2010

Breeding confirmed

One was singing in Lower Millcombe on 6 Jun and breeding was confirmed when an adult was seen carrying food in St John’s Valley on 17 Jun and an adult female with a brood patch was trapped there on the same day. Fledged young were seen near Brambles on 14 & 16 Jul. The only previous instances of confirmed breeding on Lundy occurred in 1934 and 1935.

2011

Breeding season

Although birds were seen sporadically during the late spring and early summer, there was no reported evidence of breeding behaviour to follow-up on confirmed breeding in St John’s Valley in 2010.

2012

High spring-passage counts

2-4 May – Counts of 50 on each of these three dates remain (as of July 2020) the highest spring-passage day-totals since publication of The Birds of Lundy in 2007.

2013

Exceptionally late autumn record

2017

Ringing movements between Lundy and north-west France

A first-year bird ringed at Donges, Loire-Atlantique, north-west France, in Aug 2015 was controlled on Lundy in Apr 2017 (see below for full details). This is the third Sedge Warbler to be ringed at the same French reedbed site in late summer and controlled on Lundy during a subsequent spring migration. Altogether, there have been six Lundy Sedge Warbler movements to or from the Loire-Atlantique, reflecting not only the importance of wetlands in this region for fattening-up prior to trans-Mediterranean and trans-Saharan flights in autumn, but also the intensive ringing effort there. Since 2002, thousands of Sedge Warblers have been ringed annually in Donges; over 10,000 individuals were handled in 2011 alone! These have generated numerous controls in other countries, the great majority in the UK.

2019

Notable spring-passage count

9 May – A count of 31 is one of the higher spring-passage day-totals of recent years (see May 2012 above).

 

Ringing:

The first two ringing movements detailed below refer to the Spanish- and French-ringed individuals mentioned at the foot of the table on p.198 of The Birds of Lundy.

Ringing control: A Sedge Warbler ringed as an adult at Coria del Rio, Sevilla, Andalucia, Spain (37°17’N, 6°03’E) on 25 Apr 2007 (ring no. Madrid N364976) was controlled on Lundy on 2 May 2007 (7 days; 1,547 km; N 5°). This shows rapid movement north during spring migration; from southernmost Spain to Lundy in exactly a week. This is the third movement shown by ringing of a Lundy Sedge Warbler to or from Spain.

Ringing control: A Sedge Warbler ringed as a first-year bird at Tour aux Moutons, Donges, Loire-Atlantique, France (47°19’N, 2°04’W) on 13 Aug 2006 (ring no. Paris 5337496) was controlled on Lundy on 3 May 2007 (263 days; 468 km; NNW 337°).
