Bats at Barlow Common

On Saturday evening I went to a “Bat walk and talk” at Barlow Common Nature Reserve, near Selby. The reserve was once a refuse tip and was a dumping ground for the rubble from Hull, when it was bombed during World War II. Now, the common has been miraculously transformed into a nature reserve, managed by Yorkshire Wildlife Trust.

The evening started with an excellent talk about bats from Ann Hanson, of the Yorkshire Mammal Group. She gave us a good introduction to bat ecology and described the species most commonly found in the area. This was followed up by recordings of bat echolocation calls. We then went out with bat detectors, to see what we could find. The best sighting was of two Common pipistrelles circling around a clearing in the woods, making almost continuous echolocation calls. We also heard occasional calls from a Noctule bat, but by the time I’d tuned in my bat detector, it had gone!



On Sunday, we had our regular monthly conservation work day at Allerthorpe Common. We brush-cut an area of dense bracken in one corner of the reserve, then moved to the other side where birch seedlings were taking over. By cutting back the most invasive plants, we hope to encourage more diversity. The heather is not yet in full flower, but soon will be. New heather is appearing in areas we have brush-cut in previous years, which is encouraging.

Collecting Tansy Seed

Image
Today I’ve been to Fulford Ings, to collect seed from tansy plants to sow next spring. Each plant produces dozens of flower heads and each flower contains hundreds of seeds, so the small amount I’ve collected will have no effect on the natural spread of the plants. I’ll aim to produce another 1000 tansy plants next year. Dead flower heads now contain ripe seed   The seed will be left to dry out in my kitchen   The new generation of tansy beetles that emerged from pupae in the summer have now gone underground for the winter – except for one, which was still wandering around! The last tansy beetle still active I was concerned that the tansy we planted in August was being nibbled by rabbits (see Helping Barn Owls and Tansy Beetles ). Today I saw that new growth has appeared at the base of the plants, which the rabbits haven’t touched, so I think they will be OK in the spring. The wild flower meadow is now being grazed by sheep. They eat tansy plants too, but the plant

Fen Bog

It’s difficult to pick a favourite nature reserve, as they’re all so different and vary so much with the seasons, but one of my favourites must be Fen Bog, on the North York Moors. It’s in a hidden valley surrounded by moorland, with a boggy mire in the centre. Volunteers pulling bracken I usually only visit once a year, when Yorkshire Wildlife Trust have a conservation volunteer work day there. This year we’ve had two days, cutting back the bracken on the valley sides which threatens to engulf the reserve. The denser patches are cleared with brushcutters while thinner and steeper areas can be pulled by hand, minimizing damage to the surrounding vegetation. It’s one of those reserves where the results of our work can be clearly seen from one year to the next. Areas of dense bracken we brushcut last year just needed a tidy up by hand this year.

Maldives 2016: Wildlife on the Island

Image
The two most common birds on the island of Dhigurah are the Asian koel and the Maldivian house crow. The koel, being a type of cuckoo, is a brood parasite and the crow is its host - the koel lays its eggs in the crow's nest. The koel is a protected species in the Maldives, whereas the house crow is regarded as a pest. Both are noisy birds. The koel is more often heard than seen, as they tend to perch in the densest vegetation and betray their presence only by their extremely loud calls. The house crow is a bolder bird. It will call loudly at passing humans, apparently in defence of its territory. Call of the Asian koel Call of the Maldivian house crow The Oriental garden lizard is often seen around the village. They are large lizards, up to 37cm in length, including a very long tail. They can move each of their eyes in different directions, like chameleons, and change colour to match their surroundings. During the breeding season, the male's head and shoulders turn
