Stoneferry to Foredyke Green along the river Hull

I wasn't planning this walk in the morning, as I was going to walk the old course of the Foredyke Green to join Hull Nats at Wilberforce Wood. In the event, a Peregrine deflected my walk and sent me up the river Hull. The forecast had been for cloudy weather most of the day, instead, there were long sunny spells and warm conditions with a very light breeze, ideal for insects. The peregrine, on its favourite building, was plucking and eating its prey, probably a Feral Pigeon. I hid behind a fence, taking photos from between the bars. When it stopped feeding, it swiped its bill clean on the edge of the alcove, and looked around. After taking some photos I left it on its ledge and continued on my new path.

I hoped that I could tick the Common Sandpipers near B&Q. The tide though, was very high and rising.An alarm called my attention, it heralded event that I don't see very often these days, the twin bridges of Stoneferry opening for a boat to pass. It was a small boat and the bridges didn't completely lift up, luckily, I thought, for the Swallows that nest under the bridge. I waved at the people on the boat as the boat passed, and waited until the surface of the river settled again. Maybe the sandpipers won't happen today anyway.


The Swallows landed on the bridge shortly after it went down. I hope eggs or chicks on the nest won't have been dislodged.

With such a high tide I thought I wouldn't risk it on the soft banks of the west side, so I walked on the East side. It a hard surfaced bank in its first stretch, with moorings and a short lane called Ferry Lane. Buddleias laden with sweet blossom dot the bank and there were a range of butterflies, manly nymphalids.

Just as I had taken this photo of the peacock a small bird flew past behind the buddleia and landed on a fence. A quick look with my binoculars and I got very excited: a Black Redstart! I managed some photos as it perched on the fence, likely an adult female. Would it be nesting nearby? It is peak breeding season for Black Redstarts, a species I hadn't seen in Hull since 2022 at Albert Dock, and also species 95 for my 100 birds in Hull challenge. The screeching noise of the cranes lifting metal of the scrapyard opposite grate against this lovely sighting, it couldn't be a more fitting habitat!

Three large old warehouses have recently been cleared in this plot. Herring anf Lesser Black-backed gulls were loafing on the ground. The warehouse to the right of the photo has several Lesser Black-backed pairs with grown chicks.
About 20 Swifts descended over the river, and disappeared again.

I continue up river until Sutton Bridge, then I head for Bude Park. Several tethered horses graze on the grassland. A new aquagreen has been created, and it looks like it was full in the winter, the field next to it bare but for a few scattered plants. I continue by ASDA into Wilberforce Wood.

The temporary pond at Wilberforce Wood is teeming with tiny ground hoppers.

I sit by the Foredyke Green Pond to have my packed lunch and do some dragonfly watching. The weather is  perfect for it, and I list 8 species on the wing.

I meet up with Hull Nats after that and we walk in a circuit around Wilberforce Wood. There are many butterflies on the wing and Roesel's and Coneheads are calling.

Urban birds at Hull. 53. Green Woodpecker

The Green Woodpecker is a large woodpecker with a green back and yellow rump very noticeable in flight. Green Woodpeckers have a shiny red cap, with a dark mask and pale iris. Their moustache is black in the female and with a red centre in the male (top shot). They are shy and elusive birds and rarely do they give good sightings.  They are more often detected by their characteristic call or 'yaffle' reminiscent of a whinnying horse. Green Woodpeckers are ant specialists, they locate ants nests and eat the ants and their eggs and larvae by probing the nest with their long-sticky tongue. On the grasslands where they feed their green plumage offers them a perfect camouflage. Their habitat includes garden lawns, golf courses, and woodland rides. They breed in holes they excavate in trees, as other woodpeckers.

Status and distribution in Hull

The Green Woodpecker is a scarce resident in Hull, with the records more abundant on the western side of Hull and around the outskirts. Likely places include Garrowby Community Orchard, Noddle Hill LNR and Wilberforce Wood. Other sites have had single sporadic sightings. Richard Broughton in his 2002 Birds of the Hull area regarded them as a very occasional species in the Hull area, but numbers seem to be increasing, with records year round. I had 16 records in the last 5 years, and just 2 in the previous 5. There are indications that they are probably breeding locally, several juveniles have been seen in Hull during the month of July in the last couple of years, like the one above in the Sculcoates area, in Sutton and at Garrowby Orchard.

Conservation and management

A Green Listed species in the UK, with increased population since the 1960s, with some range expansion to the north and east. It may benefit from a warming climate as it is susceptible to cold winters.

Note: I usually illustrate this series of posts with photos taken in Hull, however, given the scarcity of this species and my lack of passable photos, I used for the the top photo one taken at North Cave Wetlands in November 2016.

Urban birds at Hull. 52. Oystercatcher

Oystercatchers are instantly recognisable waders, with their pied plumage, black above, white below, and their straight orange bill and sturdy pink legs. Their eyes are dark red with a red ring around them. There is a lot of variation in bill shape and length, partly due to sex differences (females have a longer and pointier bill), but also individual preferences for prey. Individuals preferring worms have longer bills, whereas those favouring mussels have shorter, more chisel-like bills. Oystercatchers are long-lived birds, the record is 43 years old, by an individual ringed at the Wash. They are also quite site-faithful, breeding and wintering in the same areas year after year. Unlike other waders, they bring food to their young, so they are able to breed on flat roofs and do this regularly. The young are dependent on their parents for a longer time than other waders too. They are more limited to the coast in the winter, but they are increasingly breeding inland, where they have added gravel quarries (and roofs) to their nest sites. When inland (or during high tides) they regularly feed on earthworms from grasslands.

Victoria Dock, 22 April 2024. Two were present at the foreshore, this one with a very short bill contrasted with the other, with a very long one (top shot). Both individuals together suggest that the top shot one could be a female, and the bottom a male.

Status and distribution in Hull

The Oystercatcher is a scarce and localised species in Hull. Oystercatcher records concentrate between the end of February and July, where most records are probably of birds on passage. There has been historical breeding of very few pairs: in the eastern docks and near Hessle, but breeding has not been confirmed recently. The best place to see them is near the Siemens factory, at Victoria Dock. Some years they used Victoria Park lawns to feed. I have a surprising record at Pickering Park early one morning, but Pickering Park is quite close to the Humber so maybe this individual had moved inland to feed at high tide. As Richard Broughton comments, there are inland Oystercatcher records in several points around Hull, and being nocturnal migrants, they can be heard calling over the city during migration.

Conservation and management

Oystercatchers are Amber listed due to recent population declines in the UK, and listed as Near Threatened globally in the IUCN Red List. In the city, individuals have been seen limping due to fishing line around their legs, which could be something that the urban Oystercatchers might be more exposed to than in the wider countryside. Overall the causes of the declines are unclear, increased predation, or reduction on shellfish numbers (eg. cockle beds) could be to blame.

Strensall Common with Hull Nats

A warm and humid day with welcome, scattered clouds. We start our walk from the railway line crossing car park. There are several clumps of creeping thistle buzzing with insects, including a diverse cast of butterflies. The common is very dry, we walk on two board walks over a parched landscape, which was probably wet in the winter. An area shows the signs of fire, black ground, birches and pines with the purple moorgrass sprouting, two paths appear to have acted as firebreakers. I stand on the path and point the bat detector to the burnt area: silence. I turn round and point at the chugging calls of the Bog Bush crickets on the other non burnt side.

There is a ditch with tussocks of Purple Moorgrass by the car park. I have a look before we all assemble and quickly find a Long-winged Conehead nymph and a Bog Bush Cricket. There are also Common Green and Meadow Brown Grasshoppers. My bat detector allows me to hear the reeling of a Roesel's and chugging of Bog Bush-crickets.

We are lucky enough to witness a female Bog Bush-cricket nymph moulting. The whole process is quite fast. The next three photos illustrate it.

We are moving very slowly indeed and we reach the following car park after an hour and a half. There the heath is under open woodland and there seems to be more nymphs than adults, in large numbers. I stop trying to record each Bog Bush-cricket I see. This one got its antennae entangled and was trying to sort them out.
