This is the feather I caught and you can see why it is so light and floated in the air. Feathers have 3 main functions; flight, insulation and display. Feathers have many barbs which hold its shape, cause wind resistance and this allows flight. If you pick up a feather and tease the flat part apart then you will feel that it tries to hold together. This is the work of the barbs.The downy part traps air for insulation and buoyancy for water birds. The colour of feathers, including non-visible UV light helps in display and to attract a mate. There are several websites explaining the structure of feathers but they are all very detailed. This short video is quite interesting, particularly the second part: video here. If you would like more information then see here.
Trichomonosis can also affect other species of birds and if you would like to know more see here.
We were pleased to also see an adult Mayfly. They spend a very short time as a flying adult, sometimes just one day and then the rest of the year as immature forms under water.... trying to keep out of the way of the grey wagtails !!
This is the adult mayfly on Harriet's hand.
To see a video of the Mayfly life cycle watch this.
The Mayfly in this photo might well be the first of the two adult stages.

The Friends of Badock's Wood monitor the stream monthly for water creatures as an indicator of pollution and soon we expect to start monitoring Nitrate and Phosphate levels.
here. You can also hear various other birds in the recording including a chiffchaff. The woodpecker in the photo is probably a female because it doesn't have any red in its black moustache.
It is very helpful to be able to recognise some birds from their call because then you know what particular birds are around and you know what to look for. This is a great help. The FOBW have organised a Bird Walk on Sunday May 1st starting at 10am and meeting at the main Doncaster Road entrance. I believe the emphasis will be on bird song and it should be interesting.
The goods news is that we have a great group of FOBW volunteers who regularly give up their time to clear the wood so that we can all enjoy the beauty and also to make the wood a safer place for wildlife. Unfortunately it is almost certain that more rubbish will be dumped but the only answer is for volunteers to keep removing it.... over and over again.
I think the council will collect on Monday so it won't be an eyesore for long. As well as the volunteers who came today there are others who regularly turn out but weren't able to make it this morning.
A big 'Thank you' to all of them and certainly the 2016 Green Volunteer Award for the work done by all the members of the FOBW was well deserved.
There are many plants in the wood whose name I don't know. But they all add something to the overall picture and are just a pleasure to look at.
The mallard is the one I saw in the stream.
