Dales Young Ranger Muhammed Amin writes about his experience in the Yorkshire Dales National Park and in particular his pleasure when attending a bird box making session in Grassington.

Here he writes of his experience and what the young rangers learned on the day.

IT was a very bright sunny day. As I arrived at the National Park Centre, I could already hear the twittering of birdsong coming from the trees and I got more excited.

We started with Ian and Mark, the two bird ringers explaining their work.

Bird ringing is the process of attaching a tag to the leg of a bird with an individual identification number. The age, gender, species and wing size is then noted down. All the information collected is sent to the British Trust for Ornithology (BTO). This information helps track the movements and the life span of the tagged birds.

Next, Mark demonstrated the process of ringing a bird. A few cotton drawstring bags were hanging from a pole next to his leg, and some of them were moving. Ian explained that these were the bags that the birds were transported in from the mist nets. Mist nets were very thin mesh nets that had little shelves that birds could fall into as they flew to the bird feeder behind it.

Most birds are caught in the early hours of the day as that is when they are most active. Birds as large as buzzards and other raptors could be ringed.

Mark reached into one of the cotton bags and carefully drew out a beautiful green bird, a female greenfinch. It seemed tiny compared to his hand. He took a miniscule ring from a cord and attached it to the bird’s leg using a pair of special pliers so that it could slide up and down the leg and wasn’t pinching the bird. Next he took a small ruler and measured the bird’s wing.

Its age could be determined from the texture and shape of the tail feathers and the consistency of colour on the greater coverts which are the second layer of feathers on the wing. This particular greenfinch was hatched last year as the colour of the greater coverts was inconsistent and not the same all the way across the wing.

As Ian wrote down the information Mark opened his hands to release the greenfinch.

At first it did not move and just sat in his hands but then in a flash of green it shot away into a nearby tree. The next greenfinch was also hatched last year but it was a much brighter colour which denoted that it was a male.

It shot away like a bullet and made a wide circle above us before flying away.

After this exciting session we went to the workshop to make bird boxes. Cat explained that we would be making bird boxes for sparrows and that there would be two sides, a front, a back, a base and a roof on a rubber hinge.

We would cut the pieces and mark holes for the screws and then Cat or Rachel would drill the holes. I paired up with Tom and we immediately got to work cutting the pieces.

We decided to take a break and went to look at the bird Ian and Mark had caught. It was a beautiful vibrant blue tit. Up close the colour was amazing. I had never really noticed how bright it was.

After lunch we went to see the mist nets. The garden where the mist nets were positioned was alive with birdsong and I could also see little shadows darting about.

The mist nets were positioned next to a small tree and a clump of bushes. They were attached to two poles with a bird feeder behind them and when the sun shone on the net it became virtually invisible.

I could see how easy it would be for a bird to fall into the shelves of the net when flying towards the bird feeder.

Mark demonstrated how the bird wouldn’t get hurt in the net because the shelves were like a bed and the mesh was too small to allow the bird to get entangled.

Later, Cat showed us a beautiful bird nest that had been found abandoned. It was made from moss and branches and was so tightly wound that it felt solid. Finally, we gathered around Ian and Mark to see the last few birds ringed. Mark pulled out the first bird which was a startlingly beautiful goldfinch. Its head was a beautiful shade of red and it had a vibrant yellow on its wings.

Ian explained how some birds’ beaks are specially designed for different foods. Some are seed eaters and some like reaching into spiky bushes to pick berries. Next there was a dunnock, a bird with an amazing song and finally there was a pair of house sparrows, one male and one female.

Mark told us how eye colour can play a huge factor in identifying the gender of a bird. In some cases, the specific shade of colour of a bird’s eye is the feature that allows identification.
