June - ducklings, owls, breeding waders, rare insects...

June is typically dominated by breeding species and activity – and this June was no exception. As the weeks progressed it became clear that it was going to be a successful month for many species. Good numbers of breeding ducks had been present earlier in the season, especially Gadwall, and as the water levels receded many broods began to appear out of the swamp areas and back into the ditch network and onto the pool at Wheldrake where many broods were seen including a total of 121 ducklings. A Mandarin provided a more exotic appearance and continued the run of increasing records over recent years. Maybe they will eventually colonise the valley as Egyptian Geese have started to do, a pair appeared off site with a brood of six during the month. Grey Herons also appear to have had a successful breeding season, and as young birds fledged and left the heronry they concentrated onto the remaining few wetter areas, with up to 36 counted between Wheldrake Ings and Bank Island on the 25^th.

Two adults and a juvenile Little Egret were present in the valley towards the end of month, raising the possibility of local breeding following up to six birds present during May. The highlight of the month was a Purple Heron which flew over the reserve base at Bank Island on the 13^th, unfortunately it couldn’t be relocated over the following days. A Common Crane (or two) put in yet another appearance early in the month at the southern end of the valley and also on Skipwith Common - probably the same wandering individuals which have been appearing since late March.

Numbers of breeding waders have shown a small increase on recent years and breeding success appears to have been high this year with several broods of Curlew seen during the month. An intriguing flock of 75+ Common Snipe have also been seen at Wheldrake late in the month, which seems a little early for passage birds but would represent an interesting record if they relate to local breeding birds. Wader passage started with a trickle during the month with the first returning Green Sandpiper of the autumn at Bank Island on the 15^th, followed by 15 Dunlin on the 25^th, a Black-tailed Godwit and a Little Ringed Plover on the 28^th.

On the raptor front, yet another Osprey moved northwards through the valley early in the month, first appearing on the 31^st May and lingering in the Wheldrake Ings/Bank Island area until the 4^th June. The run of Red Kite sightings through the area continued during and several pairs of Buzzards had large young towards the end of the month. Three pairs of Peregrines bred in the wider valley area and two or three pairs of Hobbies were present, with Wheldrake Ings and the Pocklington Canal the best areas to look for them. Barn Owls continued their record breaking breeding season with 136 chicks ringed by the end of the month by which time several of the earlier broods had fledged and some females were already incubating second broods. The good run of Cuckoo records continued, with up to five males present around Church Bridge near Melbourne where at least one juvenile was present late in the month when several adults were also, and rather unusually, still calling in what appears to have been a rather protracted season.

On the insect front, it was a rather disappointing month for many species following the good showing earlier in the year. There was however a good number of Red Admirals, often the most common butterfly during the month, until the last week when a large appearance of Ringlets, Meadow Browns and Large Skippers took place. One of the highlights of the month included a Marbled White which flew through the reserve base garden on the 26^th, following last year’s record numbers.  On the last day of May we recorded the first (although expected) Hairy Dragonfly in the valley and a further handful of records continued into June suggesting this species has or is about to colonise the valley. Although the weather wasn’t always favourable to running the moth trap, several trapping days were logged with a good number of new species caught for the year, including a notable one – Cream-bordered Green Pea, maintaining a population at one of its key Yorkshire locations in the LDV.

A Hummingbird Hawk-moth seen visiting a garden in East Cottingwith on the 15^th was a notable record and the first for the year. A special effort was made to record clearwing moths around the LDV and Skipwith Common NNR which proved successful with several new locations and good numbers of Red-tipped Clearwings discovered, along with the continued presence of Large Red-belted and Yellow-legged on Skipwith Common.

Many new plant and grass species for the year were recorded throughout June such as: Amphibious Bistort, Bittersweet, Bog Pimpernel, Common Meadow-rue, Common Valerian, Crested Dog’s-tail, Cut-leaved Crane’s-bill, Fine-leaved Water-dropwort, Hedge Woundwort, Marsh Stitchwort, Marsh Woundwort, Self-heal, Timothy and Welted Thistle.
