Evenings on Skomer

The puffins are still at the Wick, but only for a couple more weeks. Last night there were hundreds, running around all over, squabbling between themselves and wheeling about in the sky. It was very easy to take photos and a quick film too. You'd think that I would have enough puffin photos by now after four months on the island but it's very easy to take lots more, they are just so photogenic.

Nights have been busy with Manx shearwaters. The cloudy weather has been perfect for them to sneak past the hungry gulls. Last week I went out at about eleven pm to see them come in to land, it was very very dark and raining quite heavily but it didn't put the birds off. I even had to duck a couple of times as they swooped past my head, it was very exciting listening to their eerie calls as they found their way back to the burrow and the hungry chick waiting inside.
If you would like to experience the shearwaters returning at night we still have spaces available in our overnight accommodation. There are rooms available in August, September and October from only £25 per person per night in August and only £20 pppn in September and October. Click here for a link to our bookings page

If you would like to see a shearwater during the day, pop into the visitor's centre at the Old Farm and have a look at the burrow camera. The chick in burrow 1 has hatched now and just be seen next to the adult bird, look for a grey fluffball. We also have footage recorded in previous years so that you can be certain to see a chick.
The egg in burrow 2 fared less well and didn't hatch, but it has still been interesting to watch the activity in the burrow with sexton beetles busy burying the dead egg.

Sexton beetle and egg
The beetle is in the lower right side of the photo and has bright orange patches on its back. Sexton beetles (also known as burying beetles) are really useful as they tidy up dead animals, burying carcasses underground to lay their eggs in.

July and August have been good for butterflies and moths, small copper butterflies and hummingbird hawk moths are my personal favourites, look for them around the sea campion at the cliffs and honeysuckle at the landing point.

Most razorbill, guillemot and puffin will have left by the end of the month, the odd few hanging around on cliffs or on the water.

Fulmar chicks seen more often as they grow bigger and parents cease brooding them. Kittiwake chicks ready to fledge by the middle/end of the month. Willow warbler and chiffchaff start passing through in small numbers.

As well as the usual butterflies look out for - wall brown, gatekeeper, grayling and humming-bird hawk-moths.

Seal numbers increase at haul out sites by the end of the month. More sightings of common dolphin and chance of seeing sunfish.

Pufflings

With all the amazing birdlife on the island I sometimes forget about the other animals, so I though I would share this picture of some shrew babies we found in Jerry's vegetable garden under a plank. They were absolutely tiny, pink squiggling blobs tucked away in this cosy nest. We quickly replaced the board so that the adult shrew could get back to them.

Shrew babies
The puffin chicks (or pufflings) are getting larger every day and over the past couple of weeks we have been ringing them. It's quite hard to get the chicks out of the burrows, and involves lying on the cliff tops with an arm in a burrow up to the shoulder feeling around for a small squishy lump. This could be a puffin chick or a pile of puffling poo! Each burrow contains just one chick, and sometimes an angry parent.

Extracting the pufflings
Puffin burrows can be two or three feet long and sometimes bend around which makes it difficult to reach the chicks. Often there can be more than one passageway in the burrow and so finding the chick takes a bit of practise.
Puffling
This little chap was too small to ring, the ring would have slipped over the foot and been lost so we put him back down the burrow. If you look at the end of the beak you can see the egg tooth which was used to chip away at the inside of the egg when hatching.
The majority of chicks were large enough to ring, we also measured the length of their wings and weighed them.

Fitting a metal ring to a large puffling
Pufflings leave the island about 34 to 44 days after hatching and make their way out to sea. The birds will not usually return to the island until they are two years old and will not begin to breed until four or five. The typical lifespan of a puffin is between fifteen and twenty years.

That's all for now,

Volunteers "monitor" Shearwaters



This week there have been a lot of people related activities so I felt it timely that we should go out and check on the Manx Shearwaters. These birds are un gamely on land but when close up and out at sea they really are at their best. Using their long wings they can pick up air currents created over the surface of the sea and pockets of updraft created by the rolling sea. The big swell has meant great views can be had from island or just off-shore. The rolling sea also meant the boat driver (me) could not really relax! The reason why the Manxies gather in rafts before coming on the island has several possible explanations. Firstly, rafting is a social activity (like Starlings) and it does look like fun. Secondly, a lot of birds may have been away from the colony foraging for food and have travelled a long way and are just too early to come ashore. The birds are waiting for darkness to fall before attempting to return to the burrow to feed a chick or change over with the partner who may be incubating.



Must dash to the landing now to count all the day trippers back off the island. Not something that should be rushed! So far we have had no strandees.

Other wildlife news - Guillemot chicks are taking their first leaps from the cliffs. Pufflings are starting to poke their heads out of the burrows (mainly in the evening) and Short Eared Owl chicks are looking quite adult like and exploring further affield (making them a bit less reliable to spot!). Plenty of Peregrine chick sightings at High Cliff. Young Chough are also seen daily.
