Welcome to the LDV NNR ringing blog, this blog is designed to share the experiences, findings and tales from a group of dedicated ringers. We specialise in conservation orientated research projects, largely focusing on wildfowl, waders, owls and birds of conservation concern, in and around the Vale of York NNR's.

NB - Whilst the purpose of this blog was initially designed to cover our nationally important wildfowl ringing activities, regular readers may have noticed the increase in posts detailing wildlife found across the valley (ranging from plants, fungi, butterflies, dragonflies & other invertebrates). Ringing posts will hopefully resume over the winter months, and will run alongside wildlife and work posts.

September round-up

The September sightings are now uploaded, click here for a full breakdown of species, including birds, mammals, reptiles, amphibians, butterflies, dragonflies, moths, insects, plants and fungi. Or read on for a snippet of how the month unfolded.

September saw the continued build-up of wintering waterfowl, with Teal being present in good numbers throughout the month, reaching 1000+ by the end of the month. By which time 200 Wigeon had also returned to Skipwith Common NNR. Both Greylag and Canada Geese numbers also started to increase with the concentration of local breeding birds. A skein of returning Pink-footed Geese flew south over Bank Island on the 21st, no doubt enroute to the north Norfolk coast. Otherwise it was fairly quiet for wildfowl during the month, presumably reflecting the relatively dry conditions throughout most of the valley.

Wader passage was at best steady early in the month but was largely over by the 20th with just a late juvenile Greenshank and lone Green Sandpipers thereafter. Wetter conditions along the Pocklington Canal corridor of Melbourne and Thornton Ings provided attractive for Common Snipe with 150+ there on the 1st, whilst Wheldrake Ings also held 50+ on the 3rd and 4th and more interesting, Skipwith had 25 on the 3rd.

Several Marsh Harriers were involved in a series of records throughout the site, including a wing-tagged bird from Norfolk - giving an indication of where some of our late summer birds are coming from. A single Red Kite was seen well at Thornton on the 11th and a male Hen Harrier flew south through the valley on the 21st. Three Peregrine were logged during the month and several Hobbies showed well at times, particularly at Wheldrake Ings. Barn Owls continued to fair well with second broods, with another six chicks ringed on the 11th.

Kingfishers have obviously had a successful breeding season with a good number of records received during the month, perhaps relating to 13 individuals, with up to three showing well at both Melbourne Arm and Wheldrake Ings. Jays were also obvious during the month as they started to roam from wood to wood in search of food, and perhaps as birds from other areas also started to move through the area. Other migrants passing through the valley during the month included a Tree Pipit over Wheldrake Ings on the 21st, whilst three late Whinchats were still at North Duffield Carrs on the 20th

Good numbers of warblers were present throughout the month with several late Reed Warblers presents towards month end, 11 Chiffchaff caught and ringed at Wheldrake Ings on the 25th (MFJ) were probably just a fraction of the total present on site that day. The highlight of the month was undoubtedly the appearance of a flock of 14 erupting Bearded Tits at Wheldrake Ings on the 27th – the first in the LDV for three years and the joint largest flock on record.

Reptiles and amphibians were recorded during the month, largely from Skipwith Common and Thornton Ellers. All three reptile species were seen throughout September, with Common Lizards showing on a number of days and two sightings of Adders and Grass Snakes, on the 25th one individual showed particularly well, pictured below.

Butterflies and dragonflies continued to be recorded throughout the month, with the majority of records coming from Skipwith Common, Thornton Ellers and the NNR Base Garden. Speckled Woods were the most recorded species throughout (72 sightings logged), whilst Peacocks, Red Admirals and Small Tortoiseshells were recorded in pleasing numbers. The three species of whites (Small, Large & Green-veined) were on the wing still, with just three records of Comma’s and a single Brimstone and Small Copper.

Skipwith Common, Thornton Ellers and Wheldrake Ings produced the majority of the dragonfly records, with the three species of darter recorded throughout the month, and in good numbers – particularly Ruddy and Common. Southern Hawkers, Migrant Hawkers and Brown Hawkers were recorded throughout, where as Emerald Damselflies were only present on a handful of dates and in low numbers – with the end of the season fast approaching for this species.

Whilst out working on site time was also taken to have a good look for other invertebrates, with a pleasing number of new species found, in particular eight new spiders such as the Four-spot Orb Weaver, Furrow Spider, Walnut Orb Weaver, Marbled Orb Weaver and the Invisible Spider.

A number new beetles were also added to the 2014 'pan' and Shield Bugs continued to be found in good numbers across the site, with Skipwith Common being a particular hot-spot. The first adult Green Shield Bug was found, after weeks of seeing numerous nymphs.

A new species of Ladybird was found on Skipwith Common - the Orange Ladybird, and another Harlequin Ladybird (form succinea) was seen at Thornton Ellers in the scabious meadow.

Two other new species of insect were found, both on the Common - Marsh Damselbug and a Staphylinid Beetle Platydracus latebricola.

Fungi continued to appear on the Common throughout September, with species such as Fly Agaric, Common Puffball, Spiny Puffball, Ochre Brittlegill and Tawny Grisette.
