White-tailed surprise

Spring is definitely here. On Ibsley Water the wildfowl have made way for the noisy black-headed and Mediterranean gulls which can be heard calling noisily overhead. Although a few ducks remain, including goldeneye, shoveler, goosander and gadwall, the majority have now departed. 

This afternoon a pair of redshank were feeding along the shoreline in front of Tern Hide whilst a pair of oystercatcher were on the island.

Black-tailed godwit numbers have decreased and a black swan seems to be favouring the north-western corner of the lake. Although I’m still waiting for my first swallow, sand martin numbers have increased hugely and watching them does not disappoint. I popped into Goosander Hide yesterday to see if any were investigating the sand martin bank and they most certainly are:

Although the hides remain closed and we have no plans to open them at present, it’s nice to know the martins are back and hopefully, if the next few months go to plan, it may be possible for visitors to catch the end of this year’s nesting season later on in the summer. We will be keeping our fingers crossed!

Reed buntings have been singing high from the willows on the edge of the main car park recently, and yesterday after leaving Goosander Hide I spotted this one sitting pretty in the top of a silver birch:

The highlight of yesterday’s walk (and something that definitely made working Easter Sunday worth it) was this sighting of one of the white-tailed eagles, high in the sky over Ibsley Water. They can cover such a huge area, you definitely need to be in the right place at the right time and have luck on your side, this was my first sighting of one of the (I’m assuming) Isle of Wight birds. Not the best photos, but they’re definitely good enough to tell what it is:

After getting mobbed by some gulls, which pushed it closer to where I was standing, it flew in the direction of Ibsley Common and the forest beyond.

Staying on the northern side of the reserve, the warmer weather has bought out the reptiles, with both adder and grass snake enjoying the sunshine. I’m still waiting for a grass snake photo opportunity, the adders have been more obliging:

Although there is some just outside the Education Centre, the edges of the footpaths past Lapwing Hide and the boardwalk are good places to keep an eye out for colt’s-foot. Local names of this flower include foal’s foot and ass’ foot, clatterclogs, horse hoof and son afore the father, with the latter name referring to the fact that the flowers appear before the leaves.

Wherever you walk at the moment it’s impossible not to hear the unmistakeable call of the chiffchaff, and with their numbers swelling on the reserve their call is turning into the back-drop of spring, along with Cetti’s warbler and blackcap.

I have managed a half-decent photo of a blackcap but will keep trying, as Steve Farmer very kindly shared his beautiful images – thank you Steve!

As well as the spring birds, it’s been lovey to see so many insects, with brimstone, red admiral, small tortoiseshell, speckled wood and peacock all on the wing. The brimstones have even posed for photographs:

The bees are also buzzing, with honeybees, bumblebees including the common carder bee and a number of different solitary bees active.

I’ve seen both tawny and ashy mining bees as well as this little one:

Smaller and less striking or noticable than the vibrant female, I think it could be a male tawny mining bee, but am not completely sure.

There are also lots of dark-edged bee-flies about. This bee mimic has a long straight proboscis that it uses to feed on spring flowers like primroses and violets. Their larvae are nest parasites of ground-nesting and solitary bees, feeding on the bee grubs. The female bee-fly flicks her eggs towards the entrance holes of solitary bee nests to allow the larvae to hatch in the right place. Once a bee-fly egg hatches, the larva crawls into the underground nest cell of a host bee where, once large enough, it attaches itself and starts to suck out the body fluids of the host species…

Elsewhere in the woodland the wild daffodils are fading and making way for carpets of lesser celandine, with ground ivy and dog violets adding purple to the bright yellow. As Jim mentioned, the tiny and easily overlooked moschatel, or town-hall clock, is also flowering, although you have to look closely to see it!

 

Although the past couple of nights have been cold, resulting in a slightly less exciting catch in the moth trap, moth species have been picking up and there has at times been a very nice variety to look at and photograph. I think the oak beauty may be my favourite, so far…

So there is plenty to see and hear on the reserve at present, and as well as making the most of what spring has to offer it has been really nice to see some of our regular visitors and volunteers who live a little further afield venturing back to enjoy the insect and bird life and a walk in a slightly different location. With pond dipping events planned and hopefully an onsite Young Naturalists meeting at the end of the month, it feels as though things may be going in the right direction…
