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, it now also features wildlife and work posts, explaining we how manage the NNR for both wildlife and people.

Sep'

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 en-route 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 Falcons were logged during the month and two or possibly three 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, and 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.

Butterflies, dragonflies and other invertebrates continued to be recorded throughout the month (see below for full species write ups), with a pleasing number of new species found, in particular eight new spiders and a number new beetles were added to the 2014 'pan'. Shield Bugs continued to be found in good numbers across the site, with Skipwith Common being a particular hot-spot.

A total of 97 moths were caught including 27 species, 9 of which were new for the year – Beaded Chestnut, Brown-spot Pinion, Brown-veined Wainscot, Sallow, Autumnal Rustic, Bulrush Wainscot, Centre-barred Sallow, Dark Sword Grass and Green Brindled Crescent.

On Skipwith Common a new caterpillar was also found and added to the moth species list - Grey Dagger.

A Humming-bird Hawk-moth was found in the NNR Base Garden on the 5th, the second reserve record following one in 2012 - particularly pleasing as the garden was designed as a nectar rich demonstration butterfly and bee garden.

OTHER INVERTS: 

Throughout the month several days were spent on Skipwith Common, where a number of new species were added to the invertebrate list. The Common is a really good place to look for spiders, particularly amongst the Juncus in the wetter areas, here species such as the Four-spot Orb Weaver Araneus quadratus, Furrow Spider Larinioides cornutus, Invisible Spider Drapetisca socialis, Lesser Garden Spider Metellina segmentata, Marbled Orb Weaver Araneus marmoreus and Walnut Orb Weaver Nuctenea umbratica were found.

Also new for the year from the Common were: Ground Beetle Carabus arvensis, Marsh Damselbug Nabis limbatus, Orange Ladybird Halyzia sedecimguttata and a Staphylinid Beetle Platydracus latebricola, a 14-spot Ladybird Propylea 14-punctata was also found on Wheldrake Ings. The first adult Green Shield Bug was found on Skipwith Common, a pleasing find after seeing numerous nymphs across the site over the last few weeks.

PLANTS: 

Skipwith Common produced the goods on the plant front as well, with 26 new species of wildflowers and grasses/sedges/rushes found. Some were completely new to us such as Oval Sedge and Long-stalked Yellow Sedge.

Common Yellow Sedge - Skipwith - 02/09

Some of the other new species for the year were, Pill Sedge, Common Yellow Sedge, Purple Moor-grass, Wood-small Reed, Narrow-leaved Buckler Fern, Jointed Rush and Early Hair Grass. Three types of the Polytrichum moss were seen: P.formosum, P.commune, P.juniperinum, along with three types of Sphagnum: S.fimbriatum, S.squarrosum, S.palustre.


FUNGI: 

During September several visits were had to Skipwith Common (the local fungi hotspot in the area), where a number of new species for the year were seen. Species such as Common Earthball, Common Puffball, Spiny Puffball, Tawny Grissette, Ochre Brittlegill and Fly Agaric are just a few that have been found recently. Fly Agaric is probably the best known mushroom species due to its distinctive look and bright red colours, making it instantly recognisable.
