Not a tour today, but a quick visit out of county to explore some sites in southeast Lincolnshire. It was a lovely sunny winter’s morning, but we knew to expect some rain in the afternoon, so we had to make the most of it.
For the last ten days a White-billed Diver has been delighting the crowds along the river Witham near Woodhall Spa. This is a true arctic species, breeding along the coasts of northern Russia and normally wintering along the coasts of northern Norway. Small numbers are regular off Scotland or the Northern Isles, but it is very rare this far south and particularly away from the coast. To see one up close on an inland waterway is a very rare event.
The White-billed Diver has been feeding along a 7 mile stretch of river and can move remarkably quickly up and down its length, so it can be a long walk at time. We stopped first at Kirkstead Bridge but were told it was heading north so drove round to Stixwould Station instead. This was the right thing to do – we lucked in and the White-billed Diver was diving just off the bank here.
White-billed Diver – a juvenile, feeding along the River Witham
White-billed Diver is a large bird, the size of a goose. However its most striking feature is its enormous bill. It is not really white (nor is it yellow – its North American name is Yellow-billed Loon), but rather a pale ivory. The neat scaled pattern of the upperparts immediately identify this bird as a juvenile, born and raised in the arctic in summer 2016.
White-billed Diver – allowed really close up views on the river
The River Witham is quite narrow which allows for very close-up views of the White-billed Diver. It was diving continuously and at times would surface closer to the near bank, despite the crowd gather to watch it. We followed it up and down the river for a while. A stunning bird to see.
After watching the White-billed Diver, we made our way round to the gravel pits at Kirkby-on-Bain nearby. There was a small crowd gathered here watching the Ring-necked Duck. A resident of North America, it is a regular visitor here in small numbers. This was a smart drake, similar to a male Tufted Duck but with a more patterned bill, peaked crown and two-toned grey and white flanks.

The Ring-necked Duck was loosely associating with a small group of Tufted Ducks and diving constantly. There were several Common Pochard on the same pit and a female Scaup appeared with them too. A nice selection of diving ducks! On another pit across the road, a juvenile Glaucous Gull was loafing with a small mixed raft of gulls.
It was still lovely sunny winter weather while we at Kirkby-on-Bain, but as we made our way south it clouded over and started to spit with rain. We wanted to visit a site for Long-eared Owls at Deeping Lakes. The birds roost on an island here, away from disturbance and it wasn’t long before we were watching them through the scope. They were tucked well into the vegetation today, which made them a challenge to see, but eventually we counted three in total.

There were lots of ducks out on the water here and we spent some time watching the Goldeneye in front of the hide. The birds were displaying, fascinating to watch as the males throw their heads back and kick their legs out, the females responding with their heads laid flat to the water. We even watched a pair mating.

It was also nice to see several Goosander here. At one point a smart salmon-pink drake swam past close to the hide.

As we made our way back to the car, it started to rain a bit harder. We wanted to have a look at Deeping High Bank, which thankfully meant we could do some birding from the shelter of the vehicle. We had been alerted to the presence of a Scaup along the river here and we spotted it down on the water with a group of Tufted Ducks as we drove along. It was a 1st winter drake, but still the emerging grey upperpart feathers of the Scaup stood out next to the darker back Tufted Ducks.

We had hoped to look for some Short-eared Owls along the bank here but the deteriorating weather put paid to those ambitions. We had to make do with an obliging Great White Egret instead.

As the rain set in harder, we decided to call it a day and head for home. It had been a very pleasant and productive visit to Lincolnshire, perhaps a place to visit again in the future.
