24th Dec 2016

Mike was out this morning and looking at the gulls in the Upper Cherwell Valley. On the hillock between the A361 and the M40, there was c.2000 Lesser Black-backed Gulls, a whopping 100 Herring Gulls and three Yellow-legged Gulls.

Steve was also out and had the Willow Tit and Marsh Tit in wood and at the Borrow Pit pool there was two adult Yellow-legged Gulls, 400 Lesser Black-backed Gulls and twelve Herring Gulls.

23rd Dec 2016: Caspian Gull

There is a longer story to this below, however I'm sure some people will find that boring! So, in short, there was a Caspian Gull and two Yellow-legged Gulls at Grimsbury today..... please look at the pictures and video. If you want to, please read the account of this patch first too. 

Early this afternoon John found a 1st winter Caspian Gull a mere 2 km from the reservoir, as the crow flies, in fields just over the county boundary in Northamptonshire (keep an eye on John's blog for information and photographs). So I thought today would be a good day to do the gull roost and maybe finally get a Caspian Gull at Grimsbury. John later told me there were hundreds of large gulls in the fields and at least 40 Herring Gulls in the Upper Cherwell Valley within the Grimsbury patch area (a very good number for the B.O.S. area).

I arrived at around 14:30. I wasn't sure where John had moved on to, I tried ringing him and it went straight to answer phone. He had mentioned going to Boddington and as it is normally a good gull roost I assumed he went there. To start with there were very few gulls, maybe 30 Black-headed Gulls and around 8 large gulls including an adult and a 2CY Yellow-legged Gull. It was otherwise dead and with a strong breeze and rain setting in I decided to seek shelter in the wood. There was little activity in there at all but there was several fresh Otter spraints under the railway bridge. 

I made my way back to the reservoir and although there were more gulls, they were mainly Black-headed Gulls with a maximum of 20 large gulls. The adult Yellow-legged was still around, there was a few Herring Gulls and several Common Gulls. It was now 15:30 and my hopes of a Caspian Gull were rapidly diminishing and to top it off it was raining again and I was getting cold. I decided to move down towards the pontoon to scan through the small gulls just in case there was a Med Gull or even something more unusual. As I was walking a large, very pale gull flew in and settled amongst the Black-heads. I watched it land, looked through the binoculars and was delighted to see a Caspian Gull sitting on the water! I got a good look and a few photos and the bird moved. I lost it in amongst the now hundreds of Black-headed Gulls squabbling over some bread someone had thrown out for them. I was over the moon as I think this is the first time Caspian Gull has been recorded at Grimsbury. I tried phoning John and it went straight to answer phone again... Sh!t!. I thought I caught a glimpse of the Caspian Gull sat on the water so walked back up but couldn't see it. I turned around and there was John walking towards me. I was absolutely gutted for him assuming the mega, first for patch bird, had now left. I assumed his phone battery was flat but it wasn't, there was clearly a signal issue not allowing me to connect. Oh dear... Anyway, we kept scanning and luckily John re found the gull and we enjoyed further good views and we were both extremely happy to get a patch tick. 

At first I had thought the bird was a first winter and I have to admit my experience with gulls and ageing gulls isn't that great. I also assumed it would be the same bird John had seen earlier in the day. Well, why wouldn't I? In the failing light John noticed it wasn't the same bird as earlier and thought it was a second bird, he even mentioned it may be a second calendar year bird. My photographs of the bird are awful, but after putting the news out and a link to my YouTube video on the Oxonbirding blog, Ian text me to say well done on the find and confirmed that the bird is a 2CY and not a 1st winter (thank you Ian). In hindsight, looking at John's photos and my photos/video of the two birds, they are clearly very different.

Another reasonable week for sightings. On Tuesday John had five Gadwall, a drake Tufted Duck, a Snipe over and a ringed Black-headed Gull (white ring but unfortunately it flew before the code could be read). Wednesday John had a drake Pochard and on Thursday there were flocks of thrushes moving, a male Blackcap and a Greylag Goose. Saturday morning a Herring Gull and a Yellowhammer were also seen by John.

Today Steve adult Yellow-legged Gull and Herring Gull and in the afternoon Mike had a rather unusual sighting of an albino Herring Gull.

04th Dec 2016

There was a little bit more variety this week. Two drake Goosanders were seen by John on Tuesday and one by Steve today. The Greylag Goose has been seen a few times, so it obviously decided to stay around a while. A Tufted Duck was on the reservoir and a Marsh Tit was in the wood yesterday. I did see a second bird that may have been the Willow Tit but it was only seen briefly and didn't call. Edit: Today Colin saw two Willow Tits along the southern edge of the wood.

Up the valley yesterday there were lots of gulls gathered and I saw five Herring Gulls. Today Steve saw four Herring Gulls and an adult Yellow-legged Gull amongst c.300 Lesser Black-backed Gulls, which (assuming it was the same bird) I saw later at the reservoir along with fourteen Herring Gulls. That is a really good number for here and certainly the most I've ever seen here.

27th Nov 2016

It has been a very quiet week, even by Grimsbury standards. The highlights all came on Sunday with a Greylag Goose flying over circling a bit but choosing not to land and a 2CY Yellow-legged Gull in the morning. In the afternoon Mike did the gull roost but there were much fewer birds than before with one adult Yellow-legged Gull, three adult Herring Gulls and only one Common Gull. (Yes, they really were the highlights!)

Many thanks to Dave Fuller for the photos below taken today, we needed something to brighten this blog up!

20th Nov 2016

A fairly quiet week again. The number of Great Crested Grebes has risen to six and there was five Herring Gulls around on Monday. John had a Yellow-legged Gull at the reservoir in the week and again today and I had three at the Borrow Pit pool up the valley yesterday. There was also three Ravens up the valley yesterday. There has been no further sightings of the Otter this week, although I'm not sure if people have been looking for it, but there was fresh spraints yesterday from earlier in the week.

13th Nov 2016

John visited yesterday and saw the Willow Tit along the river, had a Herring Gull at the reservoir and a Skylark went over.

This morning john and I were out early looking for the Otter, but it didn't show today. Steve and Colin found two drake Gadwall on their walk up and were joined by a pair of Wigeon. We have had a nice few days of wildfowl records, by Grimsbury modern day standards anyway! Steve and Colin also had a 3CY Yellow-legged Gull at the Borrow Pit pool.

Mike and Colin were at the gull roost this evening and had fifteen Herring Gulls, a  Yellow legged Gull and about 1500 Black-headed Gulls, plus the usual Lesser Black-backs and a few Common.  The two Gadwall were still present too.

11th Nov 2016: Otter and Goosander

It has been quite a good week so far really and far more interesting than the last few. The biggest highlight was that an Otter was seen in the river twice this week. John saw one Tuesday morning go downstream from the wood and I saw one (I assume the same one) this morning in the same area by the railway bridge. There has been a lot of spraints again recently so there is obviously a lot of activity in the area at the moment but seeing the animal itself is a real treat.

On Monday John had a Red Kite over, three Snipe in the cattle field Tuesday, on Thursday afternoon and this morning I had a drake Goosander and John also had two Shelduck over this morning. When people have had a chance to look at the gull roost there has been little of note, with only Black-headed Gulls, Common Gulls and Lesser Black-backed Gulls seen.

Overall, a pretty quiet week again. John had a Lesser Redpoll over on Wednesday and a Marsh Tit, Willow Tit and Chiffchaff were still in the wood. John had a 2CY Yellow-legged Gull at the reservoir a couple of times in the week and I had one at the Borrow Pit pool on Saturday. John also had the hybrid at the reservoir briefly on Saturday.

Mike was out this evening at the reservoir and had a first winter Great Black-backed Gull, a very good bird for here. There was also thirteen Herring Gulls (a very good number for here), two Yellow-legged gulls and about ten Common Gulls.
