September review

Mick sums up the latest month....

''WOW, what a month! With some 1155 birds ringed this month of 37 species I think you could say its been a busy month and the second highest monthly total we have ever had. It started well with the 3rd producing
165 new birds the highlights being 57 Whitethroat, 35 Blackcap and 15 Chiffchaff and ended with a fall on the 27th producing a good mix of birds including 30 Reed Bunting, 29 Chiffchaff, 25 Blackcap, our first Grey Wagtail for the year and yet another Spotted Flycatcher, the third of the year, when they can be described as intermittent at best is a great result. We also controlled a Chiffchaff and a Reed Warbler on that day, an addition to the Blackcaps we controlled on the 20th and 24th. It would be great if they both came from the same part of the country as it would possibly give us an indication of where the migrants came from that day. The rest of the month produced a lot of highs and lows with an unexpected catch of Swallows and Martins between the 12th- 21st , this was a period of time when the weather was dank and overcast together with a persistent westerly wind. Each morning we went just after first light and Swallows and Martins would turn up flying up and down the hedge line in search of food so we erected nets to catch some and were fairly successful managing to catch some 126 over the 10 day period. A great result as we are usually not very successful at catching them. Meadow Pipits have been about 10 days late in arriving this year possibly due to a late breeding season due to the cold spring so the catching of the species did not start till the 21st and since then we have caught 72. A little disappointing but not bad as very few have moved through up till now. It has to be said the real stars of the month have been Chiffchaff and Blackcap with 245 and 236 birds being caught, these birds respond to sound lures very well especially for the first hour or so after dawn, try it and join in the fun !!!!
Finally on the 28th we caught a Redwing, the first we have ever caught in September and the earliest by about two weeks. We are hoping now for October to continue in a similar way.''

Hirundines galore!

After seeing the weather forecast for Saturday, Mick and I decided that we would be better ringing on Sunday. I awoke at 07:30 on Saturday to a mizzley morning that soon cleared. It looked like we had missed an opportunity as Sundays forecast had changed to windy at 10:00 and rain at 13:00.
I arrived at 05:30 this morning to meet Mick, Dave and Dawn. We were greeted by an 8-10 mph SW breeze which was fine as the boundary hedge gave us some protection for most of the morning.
Early rounds produced the usual Chiffchaffs and Blackcaps but after a clear sky lastnight it looked like most migrants had passed through with very few warblers.
At 09:00 the wind picked up and those nets affected were taken down. At 10:00 it started the rain and so the remaining nets were taken down. However, Mick had noticed that whilst taking his nets down a large movement of 200+ Hirundines were being forced to feed close to the ground.
After the rain had quickly passed a few sheltered spots from the increasing wind were located on the NE side of a boundary hedge and three 30' nets were set up. After 2 hours we had accumulated 15 House Martins and 9 Swallows which gave us a total of 49 new birds for the day.
Whilst taking the last nets down Dawn stumbled across this Elephant Hawkmoth caterpillar looking for somewhere to spend the winter.

Friday 13th Sept

Mick and I arrived at the reservoir at 05:00 yesterday morning to be met by low cloud and fine drizzle. The rain was forecast to clear throughout the morning so until then a cup of tea was in order until it passed.
After 30 minutes the cloud started to break up so we took to the task of erecting the nets.
A good movement of warblers was soon noted and Chaffinches are now starting to make their presence in good numbers with double figures regularly seen on the disused railtrack all day.
Most warblers ringed were Chiffchaffs and Blackcaps with the Reed Warbler, Sedge Warbler, Garden Warbler, Whitethroat, Lesser Whitethroat and Willow Warbler making up a full cast of the resident breeding warblers.
Ageing Chiffchaffs in autumn is fairly straight forward. The freshness of tail feathers is one criteria used to determine their age. Adults replace their whole tail during a complete moult whilst juveniles usually retain theirs which by autumn become abraided and chipped at the tips. However, it is not uncommon to find juveniles with replaced central feathers which then show a contrast with dull old ones and darker new ones. The picture below shows a tail of a juvenile Chiffchaff with a fault bar across the tail. The central tail feathers have been replaced with much darker and greener edged adult type feathers along with the outer two on the right side of the tail, R5 & R6.
If only they were all this easy!

Tuesday 4th Sept 2013

Ed and I returned from Gibraltar Point BO after a ringing opportunity weekend. We had a great time and a chance to meet new people and see some old faces. A special thanks to George Gregory, Mick Briggs, Mike Archer and Nigel Judson for all their efforts to make our time there an enjoyable one.
Unfortunately just before we arrived, the wind had changed from a north-easterly to a south-westerly which meant that we were denied the opportunity to see European mainland breeders such as Wryneck and Red-backed Shrike which were both trapped a week before.
However, we had the chance to see common migrants such as Yellow Wagtail, Common Redstart, Swallow and House Martins in the hand. The bird of the weekend for us was a juvenile Greenland Wheatear, I have trapped and ringed a few of these myself on a field opposite my house but a large supermarket has now put a stop to that.
Mick and Dawn had been out ringing on Saturday whilst we were away and managed to ring 64 birds including 19 Whitethroats, 11 Blackcaps, 4 Garden Warblers, 5 Sedge Warblers and the 2nd Spotted Flycatcher for the year.
Having an extra days holiday I took advantage of the good weather forecast for Tuesday and met Mick at the railtrack at 04:30. A low mist was hanging around on arrival and we quickly got our nets up. We experienced one of the best days for autumn migation ever at Stanford. The low mist had downed the birds overnight and there were hundreds. Once the mist had lifted the birds had started moving and during the first net round birds were going into the nets whilst I was extracting them from the nets.
It was a rare opportunity to see migration on our local patch on a scale like this!
By the end of the day we had processed 238 birds with good numbers of Whitethroat and Blackcap.

New / Retrap
Wren 3/1
Dunnock 2/3
Robin 5/2
Song Thrush 1/0
Sedge Warbler 2/1
Reed Warbler 10/3
Lesser Whitethroat 2/2
Whitethroat 57/14
Garden Warbler 1/3
Blackcap 35/16
Chiffchaff 15/3
Willow Warbler 3/0
Long-tailed Tit 1/6
Blue Tit 10/14

Treecreeper 1/0
Tree Sparrow 1/0
Chaffinch 3/2
Greenfinch 1/0
Goldfinch 3/0
Bullfinch 1/0
Reed Bunting 6/2

So birds are finally on the move as migrants start heading south through Stanford.
At the other end of the scale tits are in very low numbers and Tree Sparrows have virtually disappeared.
Treecreepers look like they are having a success this year with 24 ringed already.

Wednesday 14th August - Draycote Water


Ed spent a morning at Draycote Water on Wednesday...his story.

Today I managed to squeeze in a trip to Draycote water just to the south of Rugby.

Birding usually presents it’s own challenges but today I had the added extra of the schools being closed for the summer holidays. Lots of young ones now being exercised by their parents.

After setting out from the café, heading in a counter clockwise direction and trying to maintain a healthdistance from the family behind me I did manage to see Great Crested Grebe, both adult and juvenile, Pied Wagtail, Crow, Swallow, Coot, Black Headed Gull, Cormorant, Wood Pigeon, Tufted Duck and was over flown by about 25 Greylag Geese.

After the first ½ mile the families started to turn back making the road a little quieter. After leaving the dam wall is wasn’t too long before I found the bird hide and spent quite some time sat in there watching the world go by.

Just after taking my seat in the hide I was quite pleased to see a Kingfisher go by, one of the few that I have seen so far this year. In front of the hide there were mainly Tufted Ducks, GC Grebe, Coot and the occasional Moorhen passing by. The feeders there were pretty much dormant, only the occasional Blue or Great Tit visiting. However a juvenile Chaffinch did make a brief appearance and it could clearly be seen to be moulting though the pink male chest. Other than a Dunnock in the undergrowth nothing else was to visit the feeders. Just prior to leaving the hide a small group of Teal came along,  feeding by the reed bed.

Continuing my journey, I spotted Common Sandpiper along the northern shore line but saw several others dotted around as I walked on. Another surprise for me was the appearance of a Red Admiral butterfly, probably the first I have seen this year.

Crossing the dam wall on the western side a bird flew up showing a clear white rump, “Wheatear” sprang to mind but was quickly dismissed. A few more yards down the dam wall another one flew up, this time definitely Wheatear. A quick scan of the rocks through my bins revealed a well spread group of three. I managed to get a quick photo, not very good,but I think you can see what it is. The Wheatears were the highlight of the walk.

On the southern shoreline there were mainly Tufties and Coot with young. Getting back closer the café I came more into contact with families again and not much else could seen.

Finally getting back to the starting point I put my feet up in the café for half and hour whilst tucking into a pork and brie baguette.

Leicestershire 68 v Northants 84

Over the last few years we have set up our moth traps along the old rail track or within the reservoir perimeters to see what species are around. These areas have the usual flora expected such as Ash, Oak, Hawthorn and Blackthorn but no phragmites. So with this in mind I decided that I would try the moth trap on the Leicestershire side of the reservoir where there is a large reedbed.
On Friday 9th August I arrived and donned my waders then made my way to the reedbed to set up some nets to attempt to catch some Swallows coming in to roost. I set five nets in the reedbed and on returning to the car Mick arrived to join me. With two more nets erected we got to the task of setting the moth trap and an additional light and white sheet. The main trap was set as near as possible to the reedbed to see if we could attract some reedbed species. The sheet was set near the base to give us something to do between visits to the trap.

Base camp
On checking the mist-nets before dusk we found that we had managed to catch a single juvenile Swallow along with six Reed Warblers, 1 Sedge Warbler and 4 Reed Buntings....... not exactly the roost were we hoping for! These were all bagged up and kept overnight in a safe place for ringing in the morning as by now the light had faded.
The sheet was already starting to attract large numbers of small insects but not many moths but the trap was now bringing in good numbers of Lesser Broad-bordered and Lesser Yellow Underwings.
30 species of micro and macro were recorded including 3 species of Footman, double figures of Flame Shoulder and Double Square-spot. Pebble Prominent, Dusky Thorn, Scalloped Oak and Ruby Tiger were nice examples. One reedbed specialist trapped was micro Chilo phragmitella, although a common species it was nice to see something other than the usual woodland species.
Dave arrived just after 04:00 to replace Mick who was travelling around to the Northants side to ring with Ed, Dawn and Simon where they set their nets on the opposite bank. I think they enjoyed themselves over there as we heard chuckles of laughter from across the water all morning!
Altogether, there were 152 birds processed with 84 on the Northants side and 68 on the Leicestershire side, an excellent day for both teams.

Bird days and moth nights

The first two weeks of August have seen warm and calm days which have been great for ringing. The number of warblers are steadily increasing as Whitethroat's in particular look like they have had a decent breeding season with 250 ringed up to date. Mick and Dave got the ball rolling on the first day of the month with their nets covering a corner of the bay including the feeding station. Surprisingly, 32 birds from a total of 41 were warblers in an area that would expect good numbers of tits and Trees Sparrows.
The following night was a planned moth trapping session so Ed, Dave and I met on the Friday night and set up camp on the rail track. All nets were erected and furled ready for the early morning start. The moth night was another success with 51 species of micro and macro recorded.
We were up bright and early at 04:00 to open the nets which then gave us a few minutes to check the moth trap and pot-up any worth photographing. A selection of these are shown below.

The bird total was not great with just 45 birds processed as our reward.
