Garden Warbler, 25th May  2019

It’s difficult to generate much enthusiasm for keeping the blog up to date at this time of year. Spring migration is all but over and the hope of an exotic, off-course migrant has passed. Being located in a bay, the Ley will never attract the numbers and variety of migrants drawn to a coastal headland so it’s bread and butter ringing for the next couple of months. By that I mean concentrating on the breeding birds and their offspring and dealing with a high proportion of re-traps compared to new birds.

Dawn is currently around 05:30 and the early starts and long hot days don’t improve my creative writing skills either! There are advantages though as the ringing tails off by midday, giving me the opportunity to maintain the net rides at my leisure. I currently use 210m of net ride and the damp conditions in the reserve lead to prolific plant growth, despite the surrounding countryside starting to wither as we experience a prolonged dry period. I have ringed 17 Blackbirds this month – all adults – presumably seeking softer ground at the Ley due to the lack of rain elsewhere. Back to the point. All this plant growth needs to be kept under control or the reedbed rides can disappear entirely within a month or so and I’m feeling quite self-satisfied that they are all fully operational. Marsh ride requires a bit more work to clear the grass that springs up between and ultimately obscures the boards but, that apart, the rest of the rides are looking pretty good.

I have lumped together the totals for the last two visits. There’s nothing out of the ordinary but I have been able to confirm that there are at least two pairs of Cetti’s Warblers present in the ringing area and that a pair of Garden Warblers appear to be breeding for the second successive year. 88  birds of 15 species were trapped: 12 Blackbird, 5 Blackcap, 4 Blue Tit, 2 Cetti’s Warbler, 4 Chiffchaff, 6 Dunnock, 1 Garden Warbler, 1 Goldfinch, 2 Great Tit, 3 Long-tailed Tit, 31 Reed Warbler, 1 Robin, 9 Sedge Warbler, 2 Song Thrush and 5 Wren.

Friday 10th May 2019

South Milton Ley seemed a little tame today as I made my first visit after returning from a 10-day birding tour of Bulgaria. The trip had been organised by BirdID Norway (see links) and subsidised by the Norwegian government. Costing just £260, 215 species were recorded in total with 120 on the last day alone and 20 species of raptor. Migration was in full flow with many flocks of pelicans, storks and various raptor species passing overhead. We also managed to get to grips with a few species, which had eluded us on our previous visit, including Black Woodpecker, Nutcracker, Thrush Nightingale and Collared Flycatcher.

Migration was certainly not in full flow at the Ley today and re-traps dominated the birds caught. Many of these were warblers returning to breed at the site. The net rides required a fair bit of work before I could open the nets as the Hemlock Water Dropwort, which is prolific around the margins of the reedbed, had grown considerably in my absence and the first new growth of the phragmites was also beginning to appear. Fortunately, the contractor who maintains the paths around the drier, eastern end of the reserve, also mows my two net rides there, which saves me a lot of effort. At the end of the session I cleared the net rides at the wetter, western end of the reserve. These are easier to maintain as the higher salinity prevents anything but phragmites from growing and the young shoots are easily dealt with using my trusty, rechargeable hedge-trimmer.

Lower Marsh Ride, May 2019

There were 13 new birds and 23 re-traps: 4 Blackbird, 3 Blackcap, 3 Blue Tit, 2 Cetti’s Warbler, 3 Chiffchaff, 4 Dunnock, 1 Great Tit, 1 Great spotted Woodpecker, 1 Long-tailed Tit, 3 Reed Warbler, 4 Robin, 7 Sedge Warbler.

Saturday 20th April 2019

With crystal clear skies overnight, a full moon and a light NE breeze there was little reason for migrants to stop or linger at South Milton Ley this morning. Nevertheless, I was greeted by birdsong everywhere with the first Reed Warblers of the year and at least three Grasshopper Warblers reeling in different parts of the reedbed. The ringing was steady throughout the day but tailed off as temperatures rose. 34 birds were trapped in total: 7 Blackcap, 1 Blue Tit, 3 Chiffchaff, 2 Dunnock, 2 Goldfinch, 1 Great Tit, 1 Long-tailed Tit, 1 Reed Bunting, 3 Reed Warbler, 9 Sedge Warbler, 1 Whitethroat, 2 Willow Warbler and 1 Wren.

 I had to make a temporary repair to the boardwalk across Marsh Ride as some of the pallets supporting the boards had rotted and collapsed, allowing the boards to sink and water to come perilously close to the top of my wellies. When I returned to admire my handy work, I spotted an eel in the vegetation. At first I thought there were two. It was so close I was able to touch it before it emerged and slowly made its way along the net ride. It was over a metre long, which is about as big as they get! Unfortunately my camera was back on the ringing table!

Wednesday 17th April 2019

Another cold and blustery morning with a brisk NE breeze. Not many obvious migrants about apart from a group of Swallows and a few House Martins hawking for insects around the STW. 45 birds were trapped: 3 Blackbird, 12 Blackcap, 9 Blue Tit, 4 Chiffchaff, 1 Dunnock, 1 Jay, 1 Sedge Warbler (the first for the year), 3 Willow Warbler and 1 Wren.

Tuesday 9th April 2019

A cool spring morning with a light NE headwind dropped a few migrants into SML today. 60 birds were trapped: 2 Blackbird, 11 Blackcap, 3 Blue Tit, 2 Cetti’s Warbler, 15 Chiffchaff, 5 Dunnock, 1 Long-tailed Tit, 1 Robin, 1 Song Thrush, 1 Reed Bunting, 1 Robin, 1 Song Thrush and 19 Willow Warbler. Most of the Willow Warblers were long-winged (presumed males) and laden with body fat. One bird with a 70mm wing, weighed 11.3g, the heaviest I have encountered to date and sufficiently heavy for me to check the calibration of my digital balance!

On the 14th August 2018 I ringed a number of Sedge Warblers at South Milton Ley. I’ve just heard that one of these, a first year bird, was controlled at Sandouville, Seine-Maritime, France, 311km ESE just two days later and then, amazingly trapped for a third time at Mars-Ouest, Sant-Philbert-de-Grand-Lieu, Loire-Atlantique, France, a further 330km SE on 23rd August. What are the chances of that? Time to buy a lottery ticket I think!

Cirl B 2

With high pressure well and truly established, a sharp overnight frost greeted me when I arrived at South Milton this morning. After a bone-chilling hour erecting seven nets with cold, ice-covered poles, the sun rose to herald a beautiful spring day. Birds were few and far between, with no visible migration and the weather giving little reason for migrants to linger anyway. Despite this, 28 birds were trapped: 2 Blue Tit, 3 Cetti’s Warbler, 9 Chiffchaff, 2 Cirl Bunting, 3 Dunnock, 3 Goldfinch, 1 Great Tit, 1 Reed Bunting, 1 Robin, 1 Song Thrush, 1 Willow Warbler and 1 Wren. The two Cirl Buntings, both males, are the first for two years and the Willow Warbler is the earliest one I have ever caught at SML.

Pollen

The spring equinox heralded an end to the string of storms, high winds and wet weather, which had been battering the SW for the previous four weeks. With the jet stream finally moving north and benign weather forecast, I made an early start and headed back to South Milton Ley. In the event the forecast was off the mark and I was greeted by low cloud and persistent light drizzle. Arriving at 06:30, it was two hours before the weather cleared and I could open the nets.

The conditions were not conducive to migration and just 15 birds were trapped, half of which were retraps. Amongst them was one lingering, wintering Chiffchaff and one obvious newly arrived spring migrant, its face encrusted with pollen, presumably picked up somewhere in southern Iberia. The total included 4 Chiffchaff, 1 Cetti’s Warbler, 2 Reed Bunting, 2 Great Tit, 2 Blue Tit, 3 Long-tailed Tit and 1 Blackbird.

Monday 25th February 2019

I took advantage of the easterly element in the wind today and strung up four nets in a row beside the western side of the sewage works. Normally, and frustratingly, the prevailing SW breeze up the valley concentrates the midges (and the Chiffchaffs) at the eastern end of the STW, where a public footpath makes netting impossible. The total catch was a respectable 48 birds, although only 19 of these were new. The total included 28 Chiffchaffs, a winter day record for the site, and 1 new Bullfinch, Reed Bunting and Goldfinch.

Other birds of note around the reserve were 3 singing Cetti’s Warblers, 2 singing Cirl Bunting, 2 Water rail, 2 Tawny Owl, 1 Sparrowhawk and 1 Great Spotted Woodpecker.
