A bit of a mixed week at Ham Wall this week with some glorious weather for a couple days and a miserable day yesterday. It's been busy though with lots of visitors, including families, over the half term break.
There's been plenty for people to enjoy, with the increase in birdsong of particular note. Just a little reminder that spring is on the way. There seem to be a few Song Thrushes about, with 3 in the car park area, at least one in the footpath trees and another bird near Waltons along the rail path - all perched up high. Wrens again seem plentiful along with blue tit, great tit, blackbird and robin you can get a bit of a chorus. A Chiffchaff has again been heard singing this week. On 2 consecutive days a Red Admiral was seen on the wing in the Central Wood.
Another obvious sign of approaching spring is the boom of the bittern. Several have been heard around the Avalon Marshes including a couple with a good solid boom (one around the Waltons trail) and many others still a bit wheezy - more of a grunt (Loxtons section). Staff & volunteers will be out in the early mornings in a couple of weeks to record the number of males around the whole of the marshes - a 4.30 start is not for the faint hearted however, but so worth it once you're there.
There have been a fair few sightings too - the 1st platform offers a good wide view and therefore a good chance of a sighting. There was even a report of a bittern swimming across one of the channels last weekend. It's not unheard of but very unusual - I've never been lucky enough myself - it must look a little bizarre.
Like Bitterns, we have had Grey Herons nesting in our reedbeds in recent years, within the Waltons section. This year looks to be no different with some significant activity on a couple of islands on the left of the Tor View Hide (this will be a great place to watch them from over the coming weeks).
The 1st platform offers a fair range of species too: Mallard, Gadwall, Pochard, Shoveler, Tufted Duck, Wigeon & Teal all present. Groups of Lapwing seen flying over although less than in previous weeks and a group of 10 Snipe or more circling the reserve but the 1st platform offered good views as they flew in a tight pack. 3 Buzzard also on the wing together on Monday and a well marked male Marsh Harrier was great to see. Great White Egrets also feed in this area frequently.
The 1st platform area and Waltons has been home to Great Crested Grebes lately & they have again been seen going through their mating rituals. John Crispin has sent me the following shots and annotations - thanks John!
Male & Female approach each other in the prone position
When together they start their much seen head shaking.
The male then goes off on a wild run finishing with a great flurry
Both birds then dive and surface with weed
This is in readiness for their famous weed dance
The excited birds usually take a little time to calm down
They then fish and/or swim together
Fascinating birds to watch and extremely handsome. Plenty of fishing to be had at Ham Wall so should be able to raise a successful brood - we expect several pairs around the reserve this coming season. There smaller cousins, Little Grebes are present too - you may be able to hear their whinnying call. c150 Pochard (mainly males) seen late in then day from the 2nd platform on a few occasions - probably coming in to roost, Bearded Tits heard pinging in Loxtons.
The Starlings are still present and have been using the area distantly in front of the 2nd platform - they have been following this pattern for a few days but of course this can change so a call to the Starling hotline would be a good idea 07866 554142. The roost should begin to tail off during the month of March so there's just a little time left to see them this season.
Also this week: Water Rail spotted again from the Tor View Hide, Raven flying overhead, Great Spotted Woodpecker drumming, Sparrowhawk, Water Rails fairly vocal, Roe Deer x3 seen on the north of the reserve, evidence of Otter and Badger around the reserve and a Treecreeper seen and photographed by John Crispin by the ditch between Loxtons & Waltons.
That's it for this week. Have a great weekend!
