River Hull. Stage 9. Tickton to Leven Canal

A cloudy, but rain free day, with a relentless northerly wind. Glad I had put my winter coat on for the walk today. The walk on the straight stretch of river north of Tickton was bracing, but the company made it much nicer: small groups of Swifts flying upstream over my head, migrating north. Between the grassy bank and the river are small patches of reeds and willows, from where Reed Buntings sang their tuneless song.
On a wide bend on the river is High Eske nature reserve, a large borrow pit where the clay for the river banks was extracted and owned by the Environmental Agency. The lake, which is brackish, is connected to the river by a short canal, allowing the tide to enter it. High Eske is surrounded by thick vegetation on its western side, mainly willows, which even obscure a birdwatching screen. It has two small islands (one of them under water today). On the other island there was a large gathering of Mute Swans, many young from last year and all non breeding individuals, which probably roost in the lake. The trees sheltered me from the wind and I stop by the river side on a muddy edge. There is a rope swing, maybe people come here to swim? There are lots of midges, and a cloud of Swallows and House Martins circle low over the water snapping them up.
 I am at the edge of Pulfin Bog, a reed fen or swamp. This is a YWT nature reserve and SSSI due to it's rare aquatic plants and reed fen. It is not possible to walk along the river around Pulfin Bog due to it's waterlogged terrain and hidden ditches and springs, it is, after all, a real swamp. An drier area of Pulfin Bog, at least today, has access. I surprised a Roe Deer resting near a very large Willow. In the reed bed ahead three belted galloway cattle stare at me from behind their fence. I haven't seen anybody during the walk, and they are probably not used to seeing people.
 I stop for lunch in a sheltered corner on the shore of the lake overlooking the large island. There are many Mute Swans, which look nervous. They start to leave in small parties in the same direction, their wings sounding like fast wind turbines. I've never seen so many swans flying before.
 As I leave the trees and come out to the river side again after crossing a little bridge it becomes clear where the swans are going: to a field on Arram Carrs, where they are presumably feeding.
 I continue on the river bank. Eske Carrs on my right. Amazing how high the river is over the land. This is a very low lying area, almost sea level, now drained by a deep drain with a pump house by the river to overcome the difference in level. There used to be a medieval village in Eske, now only a farm house survives, on a 10 m high hill. The remainder abandoned and long gone, I wonder if due to the flooding these lands must have endured before electric pumps and massive river banks.
 As I am reaching Leven Canal I hear the clear notes of a Cuckoo. A midday Cuckoo, the first of the year, and a super end to today's river stage. I hang around and look for it and I see the cuckoo, flying and landing awkwardly on a strip of reeds on Leven Carrs, then flying away. I hear it again as I turn round.
 I walk on the east side of High Eske lake, less vegetated, which allows good views of the island. There is just one Mute Swan left. A couple of Common Sandpipers fly to the island from the shore, joining another two and a pair of Oystercatchers.
The rooks were feeding young and the noise is deafening as I walk by the rookery. At the base of a tree a young rook, which appears to have left the nest earlier than it should have done. It tries to fly up the tree and then crashes onto some nettles. I hope the parents find it and keep feeding it a while.
 On the home stretch back, the wind is pushing me along and I'm facing the Swifts and Swallows migrating up river. I'm now about half way up the River Hull!

A pair of Treecreepers brought food to their young, in a nest in an old willow. While the other caught insects unaware of me and flew to the nest, this one saw me and froze, giving alarm calls, probably to keep the young silent.

Noddle Hill Dawn Chorus 2017

As it is becoming customary, I headed to Noddle Hill to celebrate Dawn Chorus day, this time with tweep Helen. We arrived at this one and only nature reserve at Hull at 5:00, with enough light to see our way through the paths. A Blackcap, Blackbirds and a Chiffchaff sung from the car park, soon to be joined by nest calling Woodpigeon. As soon as we made it out of the woodland a Whitethroat sung from a hawthorn, followed by Sedge Warbler, Lesser Whitethroat, Song Thrush and Linnet. We listened for Grasshopper Warbler but it wasn't to be, maybe the cool temperatures the last few days have delayed their arrival to the reserve? A local we met said they haven't been heard yet this year, but also commented on the presence of SEO on the site this winter. Must visit the site more!
 I decided to check a pair of pheasants by a field edge and focused on a pair of Grey Partridge, my first of the year and a lovely sight indeed! In the same field, and later on the paddock four Lapwing were displaying, which I hadn't seen in the site for a while.
 The persistent mobbing call of gulls 'kyeow!' alerted us to the presence of a raptor, a cream top marsh harrier, which quartered over the reedbeds and dissappeared in the distance. Not much later a Snipe flew around a few times, and another small wader which flew away before I could identify it.
 We walked around the reserve a couple of times until 8:20 and added some nice birds to my site list: Snipe, Marsh Harrier, Grey Partridge and Shelduck. We also had a Barn Owl and a Kestrel hunting around the reserve. A great total of 42 sp. To top up the morning I had my first Swift on the way home, which takes me to 160 species this year.
We spotted two hares grazing on the pastures. They hung around long enough for photos.

Three Greylag families with goslings were gathered at the side of the lake. This gosling approached us confidently, but its dad wasn't so sure and threatened us, hissing. This family had this single gosling whereas...

Potteric Carr revisited

There has been several years since my last visit to Potteric Carr. Today I took my eight year old daughter for a visit, one of the few Mondays she's been able to come along as her school had a training day. On arrival, I was very impressed with the new visitor centre, full of information panels on the conservation work carried out by Yorkshire Wildlife Trust and its repercussions on the wider community. The visitor centre is modern and beautifully placed overlooking a beautiful pond with a wide reedbed fringe. Once the new planting around it is established, this would be a great spot for a picnic while nature watching. My only quibble is that I couldn't find a sightings board if there is one. They do keep a blog with recent sightings, but there is something special, and more immediate, about checking what's been seen on site,
Accessibility is a big plus in the visitor centre and the reserve at large, with ramps for all but two of the 13 hides and several flat, permissive paths.
It is a very large reserve, and it is hard to explore fully in a single visit. There are four way marked trails, some of these quite long. We did a combination of the the Dragonfly Trail and the Wetland Trail. My main aim for the day was to try and see or hear a Bittern, and the extensive reedbeds of the Huxterwell Marsh appeared as a good bet, as it was there where Bitterns were confirmed to have bred at Potteric Carr for the first time in 2014. This success was the result of extensive habitat management to improve and expand reedbeds in the reserve, and culminated a trend set for years before, as the reserve had supported an overwintering population since the 1990s. We visited several hides, and got great views of a male Marsh Harrier being mobbed by Black-headed gulls (top shot). Canada Geese, Greylags and Mallard had downy young, and coots were busy bringing nesting material to their nests. West Scrape hide allowed close views of Oystercatchers, Little Ringed Plovers and feeding Black-tailed godwits. As we were preparing to leave, a small wader flew in on the close bank out of sight. I decided to sit for a little while in case it reappeared and I'm glad I did as a Common Sandpiper appeared on the exposed mud very close to us.
 We finally moved onto Roger Mitchell hide, quite hungry at this stage as we had only brought a few snacks. The view is magnificent: a large expanse of reedbed in between the wetlands surrounded by trees. As we got in, a quick soft booming greeted us. After a long wait, we had a bit more booming, coming from the centre of the reedbed. It was a lifer for me, and although we had no sighting, topped a great day out. We almost raced back to the visitor centre for some well deserved lunch.

To add to the interest there is a great collection of carved wooden animal sculptures by the trails. This newt was one of our favourites.
