First Red Kite Roost

Yesterday was the first of the Red Kite roost events on behalf of the Robert Fuller Gallery. We shared cars to the location & had no sooner got out of the cars when a Red Kite was seen flying very close to the parked cars. The colours were picked out vividly against the Autumnal colours of the trees behind. In the 2 hours we were there at least 6 were seen in the sky at the same time, but many other individuals swept by at other moments. Unfortunately, due to the enthusiastic participation of 3 youngsters bombarding me with questions & anecdotes I lost count of the individual birds coming in! Hopefully, they may turn out to be leading conservationists of the future!

In addition to the flying kites we also saw a few perched in neighbouring trees, but also 200+ Fieldfare, and a few Redwings, at least 2 Kestrels & a Green Woodpecker kept returning to the same tree for a few moments. Unfortunately, it never stayed there long enough for everyone to see it through the telescope, before it bounded away to another area, where it remained hidden. There was a flyover Skylark, a Meadow Pipit, Mistle Thrushes & Chaffinches. Throughout our stay a group of Mallard laughed noisily in the background.

The views yesterday were some of the best I've seen of Red Kites locally, but none of the photos really captured the ruddy tail of this special species. Hopefully, future visits will remedy this situation. One youngster confided to his brother that "this was the best day of my life". His brother then broadcast this information to the rest of the participants! Although it would have meant more if someone aged 85 said that watching the Red Kites was the best day of his life, at least his experience may inspire the youngster to help conserve our wildlife in the future!

Ringing at Spurn

We were due to watch ringing sessions at Spurn on Tuesday & Wednesday, but the weather forecast for Tuesday was so bad, that these original sessions had to be cancelled, and the participants were asked if they could manage Wednesday or Thursday instead. Unfortunately, this wasn’t possible for most of those who had registered, but more than 80% generously agreed that their fees could still be donated to the scientific work undertaken by Spurn Bird Observatory Trust (SBOT).

Although the main emphasis of the sessions was to observe the ringing process there was also time to look at birds elsewhere on the peninsula. One of these highlights was provided on Thursday afternoon when a Pallas’ Warbler was spotted in the garden where we were witnessing the ringing. The pm crowd were spellbound as this bird, little bigger than a Goldcrest, was observed flitting among the foliage & hovering as it attempted to pluck insects from the underside of leaves. This was a ‘lifer’ for every attendee, and was also the best view I’ve ever enjoyed – even its pale rump was visible. Sadly, my bigger lens was in the car, I was expecting to photograph birds in the hand, so this beautiful image is provided by Martin Standley from another occasion.

The non-ringing highlight on Thurs am was a Firecrest which was first glimpsed through the crack of my window as it sat on the top of a bush right next to the road. The whole class were then able to see it as it flitted from one Sea Buckthorn bush to another. The bird then disappeared when a Miriam Margolyes look-alike, who had earlier also observed the ringing, and was later to gas her way round the point, turned up.

Unusually, we are able to get decent views of some Fieldfares on most of our visits. These are usually wary birds, especially when a large group is present, but these individuals were relatively confiding – perhaps they were exhausted and hungry, although the photographed bird appears to be alert.


Back to the ringing process – every bird was weighed, such as the Goldcrest below. An average weight of this species is 5.5g – any specimens which weigh less than this are released without being ringed, as it is essential that they forage for food as soon as possible, so they may put on some weight and hopefully will survive. In addition to being ringed and weighed, each bird had its wing measured, and all these details are noted in the records.

The wall of the lab was covered with pictures of star birds ringed at Spurn including: Woodchat Shrike, Great Spotted Cuckoo, Nightingale, and various Warblers amongst others. In one corner of the wall were several strings of graduated rings to fit particular species: the smallest for Goldcrests, and then others for slightly larger passerine species. Rings for more specialised ringing sessions of geese, waders and swans were kept elsewhere. Each ring is stamped with the words “British Museum”, and is given a unique serial number, so it can be traced back to Spurn – if a ring is ever recovered. Despite all the work put in at the observatory literally ringing thousands of birds ever year, only about 1% are ever recovered. Fewer are returned for tiny birds like Goldcrests, but for larger birds, such as swans the percentage which are returned is proportionally higher – people are more likely to stumble across the corpse of a swan than a Goldcrest!

In the morning sessions most of the ringed birds were trapped in a Heligoland trap, which has a narrowing funnel, which the birds are ushered into until they reach a small box at the narrow end and are carefully placed in cotton bags – a maximum of 2 are placed in each bag. These bags are then hung briefly from hooks in the lab before the birds inside are processed – ie weighed, measured & ringed it is possible to age some birds, so this Song Thrush had pale tips to many of its body feathers, which showed it was reared this year. The Robin’s mandible was opened, and when it was yellow inside this was another proof that it was a young bird; while the bird depicted had a dark inside mandible, so was an adult.

The other Friday a woman asked Autumnwatch why so many black-billed Blackbirds had suddenly appeared in her garden. Chris Packham didn’t know, but this was explained when we saw examples of both. Every year the east coast is inundated with thousands of blackbirds from Scandinavia. The young males have moulted into their black body feathers, but their bills have not yet taken on their distinctive golden hues. The priority for these Blackbirds is to conserve their energy for the long migration, and the bills will change colour over the winter. If, and when the birds live to return to Scandinavia in the spring, then they will be resplendent in their yellow bills, as without those they could face rejection by their prospective mates.

The Wednesday am session in particular was dominated by the number of Tree Sparrows being ringed. The weather conditions were perfect for huge numbers of them to head south and more than 300 were ringed on that particular day. Other birds we saw being ringed during the 2 days included Lesser Redpolls, Goldcrests, Redwings, a Brambling, a House Sparrow & a Reed Bunting.

Many people aren't aware that SBOT is a completely separate organisation to the Yorkshire Wildlife Trust who of course run the Spurn Point Nature Reserve. The ringing of birds is an expensive undertaking with the metal rings costing upwards of 10p each, & small mist nest costing more than £50, with larger ones retailing at £75. While we were there more than 300 Tree Sparrows were ringed on the Wednesday alone, and during the course of a year literally several thousand birds are ringed in total.

I would like to thank everyone from Spurn Bird Observatory Trust who made these sessions so memorable, especially to Paul Collins who gave of his time, & who explained all the interesting byways of bird migration & who provided plenty of interesting anecdotes; but also to Rael Butcher, Steve Exley, Andy Roadhouse & Barry Spence, and those we met on our travels, such as Geoff Dobbs, and anyone else I may have inadvertently overlooked.

Finally, I am also extremely grateful to those who attended the Spurn ringing session, but especially those who booked on the cancelled Tuesday session, and who were unable to attend any of the re-arranged dates, but who generously agreed that their fees could still be donated to SBOT. Therefore, I would like to single out the donations of: Jan Davie, Jackie Gilbert, Claude Hargreaves, Caroline Hunt, Gordon Kitching, Maureen Moore, Janet Park, Tessa Potter, Brian & Margaret Richardson, Alan & Ann Smith and Linda Terry. Because of their generosity, and those who were able to attend, we were able to raise more than £360 for SBOT!

Owl Recce

Yesterday afternoon I had arranged to be watching birds being ringed at Spurn, but this was cancelled because of the uncertain weather, so I went to check whether the Short-eared Owls were still showing at the venue we will be visiting soon.

Things didn't seem very promising at first - there was very little to see apart from 3 Kestrels perched high on the bushes, and a swooping Sparrowhawk just before we reached the village itself. We overheard people saying it was a poor vole year & that there had been quite a few owls but that they hadn't been seen en masse for several days. We decided to stick it out & at about 2.40 a single Short-eared Owl was seen for a few minutes being attacked by a Kestrel - kleptoparasitism in action. We decided to go for a walk, but there were no further sightings of owls, but we did see Mistle Thrushes, Skylarks, Goldfinches and a large flock of Fieldfare. I also heard a Yellowhammer and a Reed Bunting.

Eventually, we reached a small group of birders watching something from a bridge & we were rewarded with a stonking male Hen Harrier. He flew slowly, low over a patch of dried grasses between 2 small areas of young conifers when he suddenly flushed a group of small birds, which were about the size of Linnets. Suddenly his behaviour altered & he flew in a series of sharp mad circles as he tried to catch one of these small passerines. He wasn't successful and he soon disappeared, but watching his behaviour was incredibly satisfying.

We turned at right angles & walked along the bank of a dyke. There were a few Redwing & Robin noises emanating from a small group of trees, and some loud Mallard sounds coming from the other side of the dyke, but very little to see for a while. Suddenly the duck noises increased and a Short-eared Owl was seen hunting over an area of rough grassland. We watched it for several minutes & then scanned the whole area & were able to pick out a further 7 birds. The birds nearest to us was fairly dark underneath, but there were a few over the vast area of sedge which appeared to be much lighter. The 8 were seen hunting over a vast area for about half an hour, but then numbers dropped again, so on the return journey there were maybe 4 in the air at any one time. A female Marsh Harrier came over the site, but she was chased off by one of the Short-eared owls! Despite the failure to locate the Rough-legged Buzzard, a Peregrine or Merlin it was a very productive afternoon.

The reason the owls hadn't been seen in large numbers for a couple of days were the strong winds. Owls prefer hunting in calmer weather when they can hear the rustle of voles through the thick grass & when they aren't hampered by a howling gale. Hopefully, it won't be too windy when we revisit!

Faraway Filey

Yesterday we ventured the furthest north we are going this term. The long drive seemed to deter quite a few participants, as the turn-out was lower than average, but luckily there was nothing average about the birds. To land-locked West Yorkshire birders this area is the favourite of many, but to those of us in the east we tend to take the coast for granted!

The highlight for the morning group was probably the female Sparrowhawk, which kept up a running battle with Crows & Magpies. Sometimes they instigated the resumption of hostilities, but at others she harassed them first - it seemed rather a nervy way to spend your day. However, we found this was only a morning ritual as the Sparrowhawk failed to appear for the afternoon group. The group were also thrilled to see 2 Barn Owls around the nest box - one was definitely a youngster, so it looks as though they have been successful in this particular area. There were 3 species of Gull bathing: Herring, Black-headed & a single Common. Most duck species seem to be almost out of eclipse now with fine examples of a Shoveler, the ubiquitous Mallard & plenty of Teal. There were single Bar-tailed & a Black-tailed Godwits, which were great for comparison purposes, but otherwise waders at the inland location were rather thin on the ground. A pair of afternoon Snipe spotted by Jim were a welcome addition.

To increase the wader count the pm session regrouped on the beach, where we were lucky enough to get a very good view of a confiding Purple Sandpiper, Turnstones, Dunlin, a few Knot, Oystercatchers and a single Redshank. In the sea itself we spotted single Red-throated Divers & Great Crested Grebes, but several Cormorants.

It was high tide at the end of the morning session, so we tried Parish Wood for the first time. We didn't see or hear much in this new plantation, but did find a family party of Long-tailed Tits, a couple of Bullfinches, and heard a Yellowhammer, and a Meadow Pipit, but the best birds in this area were nearly a dozen Skylarks, which were both heard & seen
