Ashleworth Ham CES Visits 2, 3, 4, 2018

These three visits took place on 18th May, 28th May and 7th June. Visit 2 on the 18th was a quiet visit, with 31 birds caught which is exactly on the average for this visit. It is always a quiet visit, with the adult birds getting on with the business of breeding, territories have been sorted out, females are laying or sitting, so there is little movement. All the regular migrants were caught, and probably the most notable thing about the visit was the catching of six linnets, of which two were re-traps from previous years.

Visit three on 28th May was a day with ideal weather conditions, still and overcast, but despite this we recorded a well below average catch of 24 birds. It was notable in that no Redd Buntings or Willow Warblers were caught, and only one Whitethroat. All the Sedge Warblers caught were re-traps, so it looks as though there have been no new arrivals recently.

Visit four on the 7th June, was another good weather morning, with plenty of cloud and only a gentle breeze. The grass is now long, and it took only a few paces into the fields for us to be soaked.  The bird song by now is much reduced, but the bubbling calls of curlew, which are an ever-present feature of the early visits continued.  Male redstarts being an exception and singing well.

It is usually on visits three or four that the first juveniles are caught. With the Spring that we have had, it was no surprise not to catch any juveniles on visit three, but it was nice to find that there has been some successful breeding, as the first youngsters were caught on this visit. Four species of resident bird provided the newly fledged birds, in the form of Blue Tits, a Blackbird, Chaffinch and a Robin. Any time soon we should get some juvenile Song Thrushes, because we have had the best year ever for adult Song Thrushes with eight new birds ringed and a couple of re-traps. Unfortunately, the one Song Thrush nest found was predated before the young could be ringed and fledge. Two Carrion Crow nests along the reserve boundary have been successful with visible young in each of them.

As would be expected, all the female birds caught on the last two visits have had brood patches that indicate they are sitting on eggs.  A female Grasshopper Warbler was caught with an incubating brood patch, so they are here this year, trying to breed, despite the fact that we thought there weren’t any, as we have not heard a singing male on any visit.

Cuckoos have been very active around the site, with up to two males seen regularly, and a female heard on several occasions.

Botanically, the fields are in their prime, with lots of Yellow Iris providing splashes of colour, and the meadow sweet, the Oenanthe and the great Burnet all flowering now.
