Bridlington and Sewerby beach

I joined Hull Natural History Society for the monthly walk today at Bridlington with Robert Jaques, Jess Stokes and Gui Garcia-Sauco. It was quite cold, mainly due to the strong wind and dark and grey, but, fortunately, the rain held on until lunch time. We started in the harbour car park and explored the south beach from the harbour wall. An assortment of waders, including Purple Sandpipers, Sanderlings, Redshank, Dunlin, Oystercatchers and Turnstones, with the usual Herring and Great Black-backed gulls. The tide was on its way out, and the birds concentrated on the exposed base of the wall and on the tide line on the beach. As we walked along the wall, several very tame Turnstones were running around amongst the workers moving crates of bait, in search of tidbits.
 We then headed north to the main harbour, where we descended onto the beach now at low tide, exposing the steps and the platform at the base of the wall. On the distance over the sea, a whirlwind of birds fed, including a few Gannets and Cormorants and many gulls.
 More Oystercatchers and Black-headed gulls fed on the beach itself. We reached the beach-huts and the cliff. The wet clay dripped over the chalk cliff onto the beach in small avalanches (top photo).
 We climbed the stairs becoming more exposed to the icy wind, and were relieved when we were inside a restaurant in town, enjoying a well deserved fish and chips and a hot drink.

This was my best Purple Sandpiper shot, there were at least three of them, but the strong wind made it difficult to focus.

Three Dunlin (I think) on the harbour mud, the one at the back looks massive, also a Dunlin?

This Oystercatcher found something to eat...

...and it carried it away.

The timing was just right to go down to the north beach from the harbour.

And a just exposed Rough periwinkle.

Now is the turn of a Herring Gull to dwarf a Sanderling. This sanderling was unafraid of the gull, running around as the do close to it.

The wintering Greylag flock

The Greylag flock at Pearson Park has been up to 94 strong this winter. The flock size varies, though, some days, there are just one or two individuals, others many more. I believe groups move between East Park and Pearson Park, as I have seen some distinctive individuals, which I call 'White Head' and 'White Chest' in both places, sometimes on the same day. As spring approaches, males become more aggressive toward other geese and the flock splits up into pairs which will settle in suitable breeding areas. Greylags are found year round at East Park, but they don't breed at Pearson Park so they only turn up occasionally in the summer.
During February, I have photographed the flock in all weathers, so I thought I'd share a selection of photos.

There was snow on the 4th and the geese moved to under the trees to feed on the grass. A kind lady with a well behaved dog threw some seed at them, but the Common Gulls descended 'en masse' to grab it before the geese had the chance to register what was going on (above)

Foraging on the snowed grass.

If you look a geese for a while, it doesn't take long to realise that individuals are attached to each other. There are pairs and families which include the pair and the young produced the previous year. The group above, probably a family, marched nervously towards the water close to each other as a large dog on the loose approached. 

This inquisitive individual was part of a family of seven, who took full possession of the bread we were delivering and didn't let any other goose approach. This is a young one, still not quite one year old, note the greyish tip of the bill, or nail, which is still black in some young ones.

Families are quite successful fending off pairs. Several individuals in this family had very orange legs, which I wonder if it is a sign of being healthy.

The young one was quite chuffed of having fended off the pair at the background.

Came back in an aggressive posturing.

This individual has a distinctive flap on his belly.

Does anybody want some seeds?

Sometimes even geese need some peace and quiet. This one sat on the grass while the whole flock was some distance away being feed by people.

It is not too difficult to tell male and female geese apart. Males are heavier, taller and they have a more robust head. However, females can suffer higher mortality during incubation, and if the sex ratio is male bias male-male pairs are not unusual.

On the 10th of February we had thick fog. I counted 94 goose early in the morning grazing on the grass.

 This year the flock often includes a Canada goose, which I call 'Confused' who was probably brought up by Greylags, as it is attached to them...

...and 'White Head'

Here is 'Confused' again. He seems attached to three individuals. The source of this interspecific attachment may originate from her being adopted as a very young gosling by a pair of greylag defending their own young from her Canada parents and the gosling becoming imprinted to the greylag family. Canada seem to have longer term family attachment than Greylag, so she might still travel with their adoptive parents.

Sunny at East Park

An sunny, mild afternoon spent at East Park with the kids. The highlights were a Grey Wagtail flushed from the middle part of the lake, the presence of the two pinkfeet geese, and a singing Song Thrush. The top shot is one of these images that can only be from East Park: diving Tufted duck, Pochard, Pinkfoot and Greylag preening. A selection of photos follows.

A few Black-headed gulls were advanced in the moulting into summer plumage.

These coots were displaying at (or away from) each other. Most of the time, whey were looking away, with their wings puffed up. Given that the white shield is an aggressive signal, maybe they were courting.

I saw 'White Head' and her partner both at Pearson Park early in the morning and at East Park in the afternoon. He tends to keep a vigilant eye while she feeds.

Swan 775 still on its own.

This Coot seems to have started nest building.

Pinkfoot, one of two in the park today, in the Greylag flock by the feeding station.

A Greylag altercation, with the fighting geese in the middle with heads submerged. Both Pink-feet are on the right.

The Pink-footed geese seem completely integrated in the Greylag flock, I observed no agression, despite they keeping very close to the greylags. Here, one of them celebrates victory with some greylags. This is called, the 'triumph ceremony', when, after an altercation, pairs and attached individuals call together with stretched necks.

After things went back to normal, some geese stretched their wings.

Both Pink-feet were together, but one of them was following a greylag most of the time, with the other on tow.

Both pink-feet look now adult.

This distressed Greylag honked inconsolably, maybe having become separated from his partner.
