Nature Fact

How do birds moult? A new feather growing from a follicle in the skin gradually pushes out the old one. This usually follows a regular sequence within each feather group. Most birds choose a time of year to moult, when there is plenty of food, dense foliage to hide and no need to use up valuable energy in courtship or migration.

Nature Notes June

The majority of June delivered wet and windy weather, with only a few dry days giving respite.

The sound of a Cuckoo was heard at the west end of Hazelwood.

In mid- June, two Nightjars were seen and heard on the central heathland by the Ranger, Will Holland.

The lack of colour on the Tit species is noticeable which emphasises  the lack of caterpillars as a food source this year.

Berries have formed on fruit bearing shrubs and trees.

Nature Fact

The Nightjar, having wintered in Africa, is a Summer visitor. It has camouflage plumage and large black eyes that are highly suitable for seeing its aerial prey in poor light. Hunting takes place at dusk and dawn. With its mouth open very wide, with a fringe of bristles spreading out each side, it ‘trawls’ for moths in silent flight. The calls of nightjars, both male and female, generally delivered from a perch, are a continuous “churring” noise. The calls have been timed as lasting for more than five minutes. If conditions are right, two broods are reared during a Summer visit.

Nature Fact

Pipistrelle Bats leave their daytime roosts at dusk and are creatures of habit, tending to follow the same routes each night. They have tiny, very sharp teeth, ideally suited to chewing the soft bodies of small insects, such as caddisflies, which form the bulk of its diet.

NATURE FACT


Woodpeckers sustain a g-force of about 1,200 as it drums its bill against tree bark. A g-force measuring between 80 and 100 is strong enough to give humans a concussion. Researchers have discovered four structures of the Woodpeckers head that make it shock-absorbent :-
* A strong yet flexible bill.
* A hyoid - a structure of bone and elastic tissue that wraps around the skull.
* An area of spongy bone in the skull.
* Little space for cerebral-spinal fluid between the skull and the brain.
Each of these elements absorb mechanical shock, allowing the Woodpecker to strike a tree at a rate of up to 22 times per second with no injury to the brain.

Summer Work Parties

The Summer work parties will be held on Tuesdays rather than Thursdays, 10am - 1pm, on the following dates:-
April 17th
May 29th
June 26th
July 24th
Aug 21st

All are welcome and we will endeavour to post details of the work to be undertaken shortly before each date.

Nature Notes

A month of clear blue skies, warm sunshine and cool nights. No recorded rainfall during the month of March.

SIGHTINGS
Birds: Wood Pigeon, Stock Dove, Buzzards, Jackdaw, Magpies, Jays, Carrion Crows, Black-headed Gulls, Herring Gulls, Green/Great Spotted Woodpeckers, Mistle/Song Thrushes, Blackbirds, Robins, Wrens, Dunnocks, Mallard Ducks, Heron, Nuthatches, Chiff Chaffs, Bull Finches, Siskins, Stonechats, Coal/Blue/Great/Long-tailed Tits, Goldcrests, Greenfinches, Goldfinches, Chaffinches.
Mammals: Wood Mice, Grey Squirrels.
Insects: Bees, Wasps, Pond Skaters.
Butterflies: Brimstone, Red Admiral, Peacock.
Plants in flower: Gorse, Broom, Flowering Redcurrant, Primrose, Bog Myrtle.

A pair of Mallard Ducks have been seen at Kingfisher Creek.
Bird song has been prolific from the end of March.
Chiff Chaffs were heard in the last week of the month, having returned from wintering in Africa.
Nuthatches have been delivering their high pitch call along the Hazelwood path.

Nature Fact

Breeding for the Chiff Chaff begins from April through to June producing one or two broods. The domed nest is built in vegetation close to the ground where four to nine white eggs, speckled with purple, are incubated by the female for 13 – 14 days. Young fledge in about 14 days.

Nature Notes

After a cold start to the month February then became very mild, with no significant rainfall.

SIGHTINGS
Birds: Buzzards, Magpies, Carrion Crows, Wood Pigeons, Jays, Herring Gulls, Black-headed Gulls, Green/Great Spotted Woodpeckers, Blackbirds, Robins, Dunnocks, Song Thrushes, Redwings, Pied Wagtails, Siskins, Greenfinches, Goldfinches, Chaffinches, Bullfinches, Wrens, Goldcrest, Nuthatches, Coal/Blue/Great/Long-tailed Tits.
Plants: Gorse in flower.
Mammals: Grey Squirrels, Fox, Wood Mice.
Butterflies: Brimstones, Red Admirals.
Insects: Bees.

A small flock of Redwings were sighted from the middle of the month, having been forced to retreat the south to feed, following harsh weather conditions in the north of England.
Both Brimstone and Red Admiral Butterflies along with Bees have been enticed out into the early Spring like temperatures.
Many species of birds are paired now and showing interest in the bird boxes.
A pair of Buzzards have been seen circling together, performing courtship flights over the site.

Nature Fact

It is not known exactly what causes an animal to begin hibernation or end it, although a sudden fall in temperature is the most obvious. It is likely that hibernation ceases when the average air temperature rises above a certain level in Spring. Should a period of cold weather then return, the animal will resume hibernation until conditions improve. It has been observed that early nesting birds will abandon their nests and contents if weather conditions do not provide them with food for their expected off-spring.

Nature Notes

The unseasonal mild weather continued through the month but changed to colder temperatures in the last week, bringing sleet showers and frost. Another quiet winter month for recordings.

SIGHTINGS
Birds: Magpies, Carrion Crows, Wood Pigeons, Jays, Herring Gulls, Black-headed Gulls, Heron, Green/Great Spotted Woodpeckers, Sparrowhawk, Blackbirds, Robins, Dunnocks, Song Thrushes, Siskins, Greenfinches, Goldfinches, Chaffinches, Bullfinches, Wrens, Goldcrest, Nuthatches, Coal/Blue/Great/Long-tailed Tits.
Plants: Gorse in flower.
Mammals: Grey Squirrels.
A pair of Bullfinches which produced five young last Spring/Summer, are again active in their territory, visiting garden feeders along the Hazelwood fenceline. A sighting of a Goldcrest was very welcome, as few sightings were recorded last year when many were lost following a harsh spell of winter weather. Birds continue to night roost in the nest boxes on site. Any required repairs or replacement nesting boxes have been made during January.
