Bird-ringing at a local Country Park

I assisted my BTO trainer with bird-ringing at a local country park this morning; unfortunately my 07:30 start was delayed by 25 minutes due to an unhelpful sat-nav directing me to the wrong park entrance. I must learn to read a road map whilst driving.
On arrival at the ringing site, the first net round had already been collected and processing had started. My first bag gave me the opportunity to study a winter thrush in the hand in the form of the redwing Turdus iliacus. Redwing are characteristically winter visitors although small numbers breed mainly in Scotland. As a target bird for the ringing session a number of redwing were successfully processed throughout the morning each receiving colour ring combinations as well as a number ring.
Despite a well considered health and safety warning and precise handling instructions from my trainer - I still elected to process the next bird. Somewhat different in both its size and disposition from the redwing, the 3 ♀ sparrowhawk Accipiter nisus was to strong for my less experienced hands and the bird was passed to my trainer to complete the processing. The size of the bird had immediately suggested a ♀ and this was confirmed by its wing length being significantly longer than the max. range for ♂♂ it was aged via the amount of chestnut colouring which was still present in both its wing and tail feathers. The thumb and index finger of my left hand bore the brunt of the hawks displeasure in being handled and the power in the grip of its talons is not something I think I could easily forget.

Later in the morning I had the opportunity to process a small number of greenfinch Carduelis chloris. These birds are simply beautiful in the hand. Greenfinch can be sexed according to the amount and distribution of yellow on the leading edge of the primary wing feathers: on the ♂♂ the yellow extends all the way to the feather shaft whilst on the ♀♀ the yellow does not reach this far across the width of the primary.

Blackbird Turdus merula were also processed including a 4 ♂ whose wing length was indicative of a Scandinavian winter migrant. Blue tit Cyanistes caeruleus, great tit Parus major, dunnock Prunella modularis and a single robin Erithacus rubecula made up the rest of the morning's catch.

Blashford Lakes - birding highlights

Highlight of the day: a single water pipit Anthus spinoletta which alighted briefly on the shoreline of Ibsley Water in front of the Tern hide around 12:30. The water pipit is a scarce winter visitor to Hampshire last year having only 8 county records for December (Hampshire Bird Report 2008) - so we were very pleased to have this albeit brief encounter. Other Ibsley Water highlights included a small number of both goldeneye Bucephala clangula and goosander Mergus merganser; 13 snipe Gallinago gallinago - the only waders noted; a single kingfisher Alcedo atthis and two meadow pipit Anthus pretensis.
Elsewhere on the reserve other birds of note included 3(4) chiffchaff Phylloscopus collybita feeding over the reed bed seen from the Ivy North hide along with 1(2) cetti's warbler Cettia cetti; 2 goldcrest Regulus regulus amongst a mixed tit flock.

Candlesnuff fungus, Sparsholt College woodland floor 15th November 2009

Candlesnuff fungus Xylaria hypoxylon

Collins Complete Guide to British Mushrooms and Toadstools describes this fungus as common and widespread, growing on the dead wood of broadleaved trees (Sterry P. and Hughes B. 2009). I have it on good authority (my wife) that if you lightly flick the fungus - the spores come out of the top like smoke - apparently I missed this little trick - and the fungus itself - at the last Swanwick Lake fungi foray.

A bird in the hand

Parabuteo unicinctus
The Harris's Hawk Parabuteo unicinctus is a raptor of the south western states of USA, Central and South America - a bird of savanna, chaparrel and other semi-arid habitats. It is a social bird and will often be found hunting in small family groups, working cooperatively to exploit larger quarry. It's natural sociability making it an ideal bird to be trained for falconry (Cornell Lab of Ornithology, 2009 [Online]; The Peregrine Fund, 2009 [Online]). Peter Harvey took the opportunity today to study the species close up and in the hand when a falconer asked permission to hunt through his garden-side wood.

And what of the mystery garden 'shrooms? Phil Budd without hesitation identified the specimen I had taken along as Fairy-ring toadstool Marasmius oreades.

Those garden 'shrooms again ! Just what are they?

Remaining somewhat frustrated by my continuing inability to ID the fungi sp. growing on the garden lawn. I will be taking today's record shots along with a single fruit body to Swanwick Lakes nature reserve tomorrow to ask a local "expert" mycologist exactly what they are?

highlights of another slow wildlife weekend

A single chiffchaff Phylloscopus collybita heard calling, then seen in the tamarisk Tamarix aphylla at Southsea Rock Gardens pm
In the garden a scarlet pimpernel Anagallis arvensis displaying both a single withered flower and an optimistic new bud.

The fungi which reached a peak count of 18 by mid week, continues to defy positiive ID confirmation due to a severe lack of fungi field skills (poss. Galerina mycenopsis). Some individual fruit bodies have reached widths of up to 20mm, but most have remained below 5mm in width - these smaller caps are now shrivelled - although new fruiting bodies are still appearing at the soil surface.
Time for real wildlife experience seems meagre at the start of this college term.

little beasts and garden 'shrooms

With no time this weekend for any lengthy wildlife expedition, a quick trip to the back garden produced albeit a limited opportunity for some natural history blog activity: with two female (European) garden spiders Araneus diadematus staking claim to the south facing shrubs, soaking up today's sunshine after yesterday's downpours.
I also noticed for the first time the appearance of fungi within the lawn, with up to 8 small brown caps all less than 1cm wide poking up through the distressed sward - after a hasty thumb through Paul Sterry's "A Photographic guide to Mushrooms of Britain and Europe" - my best guess being that they are possibly Galerina mycenopsis a fungi associated with mossy lawns and grassland? I will have to keep an eye on them to see how they develop.

Not a Bird ? Sparsholt College reptile sp.

Anguis fragilis

Anguis fragilis

Taking a short (and much needed?) break from blogging recent avifauna spp. sightings, it is time to include the photo record of a slow worm Anguis fragilis found under felt in the shelter-belt at Sparsholt College on 22nd September 2009 Given the size and colouration of the slow worm (iridescent gold, with black / brown sides and a central dorsal stripe), I would identify it as a juvenile. This slow worm was not the only specimen to be found. However, the first was to swift (!) to be caught when the tin was lifted. The juv. reptile showed its contempt for disturbance by defecating in the hand.

ARKive provides a brief guide to the biology of this reptile, along with some stunning video footage of the sp. http://www.arkive.org/slow-worm/anguis-fragilis/biology.html Although any information the website provides regarding the slow worms legal status needs to be double-checked against both Natural England and UK Biodiversity Action Plan websites.

The slow worm is protected under Schedule 9 Wildlife and Countryside Act (1981).

Rare passage migrant, Hayling Island

A juv. pectoral sandpiper Calidris melanotos has showed confidingly on a small pool beside the Hayling Billy coastal path (Hayling Island) for the last three days, whilst these photographs are not the best, they do show the key ID feat. a set of streaks starting at the throat and ending in a sharp cut-off point at the centre of the breast, the belly is unstreaked and noticeably whiter in appearance; legs are yellowish to grey green. This N. American bird is a rare passage migrant in Hampshire, a second bird has also been reported this week at Keyhaven (New Forest).
