BRECKLAND: Hawfinches and hybrid ducks

Mid-February 2019

Adam & I try to get in a day birding most holidays, and decided to head down to the Brecks for this one. We opted to give Santon Downham a miss, so our first stop was by a roadside overlooking a block of forest. The weather was still overcast so we weren't confident of our chances of seeing Goshawk, but it didn't take too long before one was up. It didn't display, but instead flew back and forth a few times over the trees giving excellent views. As I stood there listening to a Skylark I realised that it was my first of the year, as was a Mistle Thrush that called and then flew off in front of us.

Next up we tried another block of forest where a feeding station has been set up in an area where Willow Tits are still present. The table was attracting a steady stream of the Blue, Great, Coal and Marsh Tits (and Dunnocks), but unfortunately we didn't see or hear any Willow Tits. A Hairy Shieldbug landed on Adam's leg whilst we waited. Eventually we decided to just walk a bit further along the ride, seeing a Muntjac and a Great Spotted Woodpecker, but not a lot else.


Our main target was a Kumlein's Gull that had been appearing sporadically in the gull roost at Lackford Lakes, but with a few hours before the gulls were due to start arriving we decided to go to Lynford first. We checked out Lynford Water in case there were any Goosander, but only saw common species (although the sound of a huge flock of Siskin was impressive). In the arboretum we quickly found some Hawfinch and got great views as they fed under the trees in the paddock. We were rather bemused that some nearby photographers seemed more interested in photographing Great Tits on some rather oddly positioned feeders on the bridge (oddly placed because people had to keep walking past them), but on our way back we found that most of them had just been taking time out from photographing Crossbills drinking from the flooded meadow.



After missing a turning we eventually found Lackford Lakes, a reserve that neither of us had visited before. We had a cup of tea in the visitors centre before heading out for a look around the reserve. The first hide we called into was packed, so we moved round to the next one, which overlooked an area called the Slough. Around 400 Lapwings were roosting, along with some common waterbirds. Whilst looking through the ducks I noticed two of the 'Mallard' accompanying the Pochard had pinkish bills. A closer look revealed that they were hybrids. Recalling my Peter Scott Wildfowl book I suspected these were Rosybill x Mallard, an ID that hybrid bird guru Dave Appleton agreed with.


With our visit already a success thanks to the hybrid ducks, we walked back to the sailing lake to watch the gulls come in. The roost was large, but lots of the birds were Black-headed Gulls rather than their larger relatives. After an hour or so we decided to call it quits - one 1st-winter Caspian Gull had flown in but there was no sign of the Kumlein's Gull. It was a light evening and we knew it might arrive later on, but both of us needed to be back home in reasonable time. Whilst watching the gulls we were also entertained by several Goldeneye, whilst a Kingfisher, Red Kite and Sparrowhawk all flew past during our vigil.

All in all we had a very pleasant day out with some unseasonably warm weather in the afternoon - thanks to Adam for doing the driving.

BRECKLAND: Lynford leaf-miner day

13th October 2018

Every couple of years the Norfolk Moth Survey hold a daytime walk looking for leaf mines, and this year it was held at Lynford. It was led by national experts John Langmaid and Brian Elliott, and attended by a large number of Norfolk & Suffolk moth folk. I attended the morning half at Lynford Arboretum, although having seen some photos it appears that the more interesting species (including two on Viper's Bugloss) were found in the afternoon at Lynford Water after I had left.

Despite the large number of trees in the arboretum, there was only a modest number of species recorded (I made it about 35), because many of the foreign trees don't have corresponding miners here in the UK. A selection of the more interesting moth mines were Stigmella basigutella in Oak, Larch Case-bearer, Coleophora laricella, Ectodemia atrifrontella or E. longicaudella in Oak bark and Stigmella alnetella (usually this species is listed as having to be bred through to confirm, but it was identified by John Langmaid who has written books about micro moths).

Of the non-moth mines, Agromyza sulfuriceps in Meadowsweet was only my second record, and there were two new sawfly mines - Metallus pumilus in Bramble and Fenusella glaucopis in Aspen.

BRECKLAND: Colletes cunicularius and other interesting insects

5th April 2018

After leaving Weeting, we called in at Lynford Water. This area of former gravel pits has a nice sandy bit of heath that is one of two Norfolk sites for Early Colletes (Colletes cunicularius), a species that Jeremy and Vanna had tried and failed to see twice before. The weather had warmed up nicely, so we were optimistic that it would be third time lucky.

Walking down the path from the car park we saw a Melangyna hoverfly. Fortunately it was one that can be identified from photos, Melangyna lasiophthalma, which was a new one for me. A pair of furry flies were mating on the ground a bit further along, but rather than Bee-flies these turned out to be a tachnid fly, Tachina ursina, which was also new.



Our target bees mainly nectar on Sallow pollen, so we moved along to check out the trees along the waters edge. Small Tortoiseshell and Comma butterflies were seen, along with two more new insects, another tachinid, Gonia picea, and an ichneumon, Diphyus quadripunctorius.



After a few 'probables' feeding high up on the Sallows, we began to see male Colletes skimming low over the turf. They were very hard to get a good look at, but further along we found some holes, and when a female emerged she was immediately pounced upon by multiple male bees. Once mating they were easy to observe, and we got great views.




After stopping for lunch we slowly made our way back to the car, checking the sallows again. There were lots of insects, the best of which were an Early Nomad Bee (Nomada leucomelaena), a Myopa sp and a Large Gorse Mining Bee (Andrena bimaculata).



A very successful trip in terms of finding our target and lots of other species of interest. Thanks to Jeremy, Vanna and Ian for their company and insect spotting skills.
