My patch dedication has been less than impressive this year, mirroring my blogging. I may have ‘phased’ in both. As previously mentioned I am not too bothered by this, and 
sure enough in the last few days something has begun to stir, and what started 
off as small forays to pick off migrants are turning into longer outings. I 
think I have timed this perfectly, particularly given all my other 
interests.
It began a week ago, last Friday, when in danger of missing 
the largest influx of migrant Tree Pipits any of us can remember for a long 
time, I snuck out on the patch early one misty morning and was rewarded 
instantly. There were three birds that day, and I saw either one, two or all of 
them, it is impossible to say. I also found a Whinchat, another year tick. I 
wasn’t able to then get out at the weekend, mainly by virtue of being in 
Belgium, but another quick raid on Bank Holiday Monday netted a Spotted 
Flycatcher and a Pied Flycatcher in under half an hour, as well as a Garden 
Warbler.  The following few days were dominated by Canary Wharf, but I managed 
to get away early on Wednesday and snuck in 5 Whinchat and a Common Redstart 
before it got dark. This really got the juices flowing and the following morning 
I walked across Wanstead Flats to Manor Park to catch the train rather than my 
usual tube from Leytonstone. During this really quite direct walk, which took a 
little over half an hour, I totted up 5 Whinchat (almost certainly the same 
birds as the previous evening), 3 Common Redstart, and 8 Northern Wheatear. To 
say I arrived at Canary Wharf with a spring in my step would be an 
understatement.
Which brings me to this morning, keener by the day, when I 
was out at 7am. With more time on my side I was able to linger for longer in the 
Enclosure. A Garden Warbler, a Reed Warbler, and two Common Redstart, one of 
which was an absolute belter of a male. Close by 4 Whinchat remained in the 
brooms, and a Hobby cruised overhead. Tomorrow is the weekend, I am in the 
country, I am not going to Cornwall/Brittany Booby-twitching, and I cannot wait!  
Bird Days.
A lot of the birds we have all seen this week are the same birds 
that have decided that Wanstead Flats is so nice that they are going to stay for 
a few days. This makes determining how many individuals we have seen very hard, 
so the best thing to do is to use the concept of bird days. We all understand 
that this multiplies the numbers, but it makes annual comparisons more 
straightforward. My totals are meagre, but the overall numbers for August are 
phenomenal.
Wheatear = 24
Whinchat = 55
Pied Flycatcher = 17
Spotted Flycatcher = 29
Common Redstart = 24
Tree Pipit = 39
So we all know that the Whinchat total is significantly 
boosted by a group of 4 or 5 birds that have hung around for nearly a whole week 
in a large patch of Willowherb south of Long Wood. Ditto the Common Redstart, 
the last few days have seen the same birds remaining in exactly the same spots 
around the patch. What can be quite illuminating however are the maximum counts, 
they at least prove unequivocally that we are getting some really rather good 
numbers, as opposed to a single bird hanging around for weeks on end.  So for 
example on one day, August 24th, there were 6 Pied Flycatcher reported. On the 27th there were 10 Whinchat, and on the 
29th 7 Common Redstart and at least 12 Wheatear. Birds obviously 
move around a patch during the day, and so this can be somewhat subjective, but we 
do try and take account of specific locations to assess the likelihood of 
duplication, and we don’t think this exaggerated. For example we would generally 
not expect birds near Alexandra Lake at the far eastern end of the patch to be 
the same birds that are recorded in the SSSi at the western end, though we 
acknowledge that it can happen. Best efforts really.
Still, I don’t know 
of another urban patch quite like it, and I am very lucky to have it on my doorstep.

 
You definitely are!
