A Confusion of LBJs

Visit The How Stean Cafe blog for flycatcher info.

IMG_5452Blackcap

A recent walk around Yorkshire Wildlife Trust Staveley Nature Reserve was a good opportunity to re-familiarise myself with those LBJs, Little Brown Jobs, that seem to appear from nowhere at this time of year determined to confuse my senses with their sight and sounds. Sight because as LBJs they all, at least superficially, look the same, as the name says small and brown. That is they usually are dressed for concealment, all wear camouflage gear, ideal for hiding in reeds, skulking in dead grass, nesting in the undergrowth. Each has its particular attire which reveals its true identification, provided that is you get a good enough view of it – you rarely do and consequently need to rely on sound for a positive identification. Well as some of you can confirm the older you get the worse your hearing becomes (I’m waiting for hearing aids) and this is compounded when almost all LBJs are summer migrants, all arriving at approximately the same time and all flitting around nonstop singing from their place of concealment. We can roughly call all LBJs warblers because all fit the bill although there are some confusing resident species which are small brown and tiny. Now however is the time for the warblers to arrive, indeed at a place like Staveley with reeds and water they are everywhere.

The first warbler to arrive is the chiffchaff which can be identified by that onomatopoeic song which literally does sound exactly like its name, chiffchaff, chiffchaff. By now they are everywhere and easy to identify provided they sing, from a sighting they can easily be confused with the very similar willow warbler, fortunately the BTO provides some identification help on their website. In the meantime familiarise yourself with the willow warbler’s song, best described as a repeated soft descending whistle, another song heard everywhere provided the habitat is right. In evolutionary terms it’s clearly not wrong since chiffchaff and willow warbler went their separate ways.

Locally we just don’t get nightingales and whilst deprived of their song one of the best songsters around, especially in the LBJ category, is the blackcap and it kindly helps us identify it because the male does sport a blackcap – I wonder how it gets its name? The female has a brown cap. The song is a delight, Collins describes it as “one of the finest – an irresolute chattering turning into clear, slightly melancholic flute-like notes at the end.” Collins also says it begins like a garden warbler, as if the garden warbler song is easily recognised by everyone. In practice many birders of increasing years struggle to distinguish between the two so turn again to the BTO website for more help. The garden warbler isn’t as easily recognised as the blackcap because frankly it’s the archetypical LBJ. Its only distinguishing feature is its dark eye which from the depths of a bush on a dull day is ….. well you know where I’m going! The basic difference in call is the garden warbler has a longer more fluty song. Maybe you should listen to the BTO video.

We should finish with the reed and sedge warbler. These denizens of the reed beds are skulking, secretive creatures, both struggle with the challenges of keeping their nesting sites private whilst at the same time attracting a mate and protecting their territories, no easy feat. You might argue with some justification that a reed warbler even takes the garden warbler’s position as archetypical LBJ, it lacks even the dark eye as means of identifying it, it won’t matter however because you rarely see it and when you do it is just a flitting glance, no more. The sedge warbler is at least recognisable if it does show itself because it has a thick white(ish) eye stripe and streaked back. It sometimes it will briefly rise above the reeds before parachuting down into cover. The reed warbler has no such distinguishing features and maybe it’s best to again rely upon the excellent BTO videos for help. Maybe I’ll mention whitethroat and lesser whitethroat another time, if that’s OK?

Butterfly Still Tumbling

Orangetip - Alan CroucherOrangetip – Alan Croucher

My last bit about butterflies – really it belonged to Butterfly Conservation – led to some of you kindly contacting me about these fascinating insects. Alan Croucher writes, “I thought you might like photos of Orange Tips. (I quite like the this one as you can see a bit of its underwing). We saw four at Lingham today when we visited. There were quite a lot of Sand Martins and Swallows around as well as three Blackcaps (two males and a female). Altogether we had around 50 species at Nosterfield and Lingham.”

Meanwhile Paul Irving writes, “Yes, butterflies had a pretty awful year last year but to suggest it was anything other than weather related would be rather premature. Some particularly those with short flight periods can be very severely affected in this way. The best way to look at butterfly trends is to look at five-year averages, that gives a much better picture of the long term. Yes, observer effort affects it too, remember in bad weather years there will be fewer of us out in the weather so annual fluctuations may be exaggerated.”

From Padside Janice Scott tells me, “I sent you my message about missing migrants last Saturday and couldn’t believe it when later that same day we saw our very own male swallow fly in. We know he is ‘ours’ as he made straight for the tiny hole that Tim has cut in the garage door as a ‘swallow door’, the main door being closed at the time. Since the weekend he has been inside every night, perched in last year’s half completed nest. We’re fingers crossed he has a mate this year, as we think something happened to his mate last year as she disappeared fairly quickly, but he stayed with us all summer, trying to attract someone else, without success. We have also now heard willow warblers around us, so there was obviously a small window for migrants last weekend although still thin on the ground. On the butterfly front, we have seen a single male orange tip around several times this week – very early for us. As you say, nectar plants are a problem when they are so early. Our garlic mustard and ladies’ smock are not yet flowering and the sweet rocket is only just beginning to open out. However this orange tip has been favouring a perennial honesty (lunaria rediviva) which is in full flower. I would heartily recommend this as a plant for wildlife gardeners – good for bees, butterflies and humans to enjoy.” What signs of spring have you seen?

Hedgehog Awareness Week

Hedgehog1 Chris HendersonHedgehog – Chris Henderson

Hedgehog Awareness Week is organised by the British Hedgehog Preservation Society and takes place every year. This year it takes place from 30 April to 6 May 2017. It aims to highlight the problems hedgehogs face and how you can help them. “There is concern at the moment about the introduction into this country from New Zealand of a trap used to kill hedgehogs, rats and stoats, which are all non-native pests in that country.  However, hedgehogs are a protected species here and anyone using the A24 trap would need to make sure they did not kill a hedgehog or they can be prosecuted. This year efforts are focussed on our strimmer campaign. We have produced waterproof stickers that we are sending to councils, tool hire companies, grounds maintenance teams etc free of charge on request (email info@britishhedgehogs.org.uk). The stickers remind operatives to check areas for hedgehogs before using any machinery. Once the group have received the stickers and sent us a pic of them in action, we can add them to our Hedgehog Heroes Roll of Honour!” See http://www.britishhedgehogs.org.uk/hedgehog-heroes-roll-honour/

As well as checking areas before cutting there are other things we can do to help too:

  • Ensure there is hedgehog access in your garden – a 13cm x 13cm gap in boundary fences and walls.

  • Move piles of rubbish to a new site before burning them.

  • Ensure netting is kept at a safe height.

  • Check compost heaps before digging the fork in.

  • Stop or reduce the amount of pesticides and poisons used.

  • Cover drains or deep holes.

  • Ensure there is an easy route out of ponds and pools.

Polluted Rivers and Surveys

Pennine Grouse Moor Survey Erroneous Say BTO!

A bird survey that was reported to have taken place on a managed grouse moor in the Pennines has been widely quoted in the media this week. The report suggested that 800 pairs of Lapwing, 400 pairs of Curlew and 100 pairs of Golden Plover were present, and that 89 species of bird were seen. These results have been used as evidence that moorland managed for grouse shooting is good for birds. These figures have been attributed to the British Trust for Ornithology (BTO), but this claim is erroneous. This fieldwork was not carried out by the BTO and did not use the rigorous statistical methods employed by the BTO in order to produce accurate estimates of this type. The organisation wishes to make it clear that the quoted figures should not be attributed to the BTO. The BTO is a charity dedicated to providing scientific information to inform decisions about birds and their habitats. Whenever possible the BTO makes its evidence available for use by all stakeholders. The BTO is the UK’s leading bird research charity. A growing membership and up to 60,000 volunteer birdwatchers contribute to the BTO’s surveys, collecting information that underpins conservation action in the UK. The BTO maintains a staff of 100 at its offices in Thetford, Stirling, Bangor (Wales) and Bangor (Northern Ireland), who analyse and publicise the results of surveys and projects. The BTO’s work is funded by BTO supporters, government, trusts, industry and conservation organisations, www.bto.org. It seems, to me, that those who wish to legitimise their annual slaughter of our wild birds and those numerous creatures that prey on them are resorting to tactics which can only serve to make the licensing of grouse moors an urgent necessity. You can’t defend the indefensible!

Alan Croucher asks, “You might be interested in the following petition regarding the culling of buzzards. Suspend Natural England licence to kill buzzards.”

Oak Beck Pollution

It seems that Oak Beck, which runs from Haverah Park, through Oakdale, Jennyfields and Knox, has some worrying pollution issues with no immediate prospects of a solution. These include foul water/sewage escapes plus ‘solids’ and flash flooding. I was somewhat surprised to learn from Keith Wilkinson of Bilton Conservation Group that Harrogate have a ‘dual flushing’ system where rainwater from roofs is directed into the sewage system to help keep the foul water/sewage moving. It seems that many, myself included, are unaware of where their roof rainwater goes and just assume it all goes into the sewer system – for those houses where their rainwater is directed to surface water drainage there can be problems when householders put ‘grey water’ down the gullies at the foot of their fall pipes where it emerges later in the local becks and contaminates them – similar to washing cars in the street and flushing the detergent/wax down street drains. Toxins enter Oak Beck at the rear of the Hydro at New Park. This can happen within 45 minutes of rain falling compared within 48 hours where rain permeates naturally through the fields, woods and vegetation. The result is possible localised flooding and maybe worse further downstream whilst the impact on wildlife has not been accurately assessed. Oak Beck is the main drainage channel for the whole of north Harrogate and, as such, is classed by the Environment Agency as ‘River’. Its water quality varies as industry and housing develop apace – but it still sustains brown trout, 3-spined stickleback, bullheads, minnow, stone loach, kingfisher and otter. It seems we have lost the last white-clawed crayfish, which were last sighted for certain in 2007. Hopefully the two New Park councillors can succeed in persuading Yorkshire Water to have a public meeting to let the residents know what plans they have to mitigate/resolve the pollution. You could help by supporting them and our wildlife. For more details search here, and here.

Swifts Update?

Charles Gibson tells me, “There were at least 60 lined up on the power lines at the bottom of the garden at 7am today (16/8/15) in Shaw Mills.” Charles has also seen house martins gathering on wires near his home.

Ann and Colin Snelson report, “Middlesmoor had swifts as usual this year and we enjoyed their screeching parties, which is such a lovely summer sound. There were definitely a few around still on 10 August, which is about a week later than normal. The other thing is the swallows which we hardly ever saw at all are now visiting the village and sometimes as many as 60+ gather on the electricity wires. This is a little earlier than we’re used to so the migrants’ calendar is certainly altered this year.” Pleasing to hear that Middlesmoor have had good numbers of swifts and swallows. Swallows in particular are in short supply elsewhere, locally.

Stephen Root reports, “Greenshank and spotted flycatcher at Hay-a-Park, plus a late swift through.”

Your Sightings

Wood Wasp: Charles Gibson reported one in his kitchen. These ferocious looking insects, which are also called sawflies, are in fact quite harmless, what looks like the world’s biggest stinger sticking out of their backsides is in fact an ovipositor and adults cannot sting. The larvae defend themselves by regurgitating a distasteful liquid from their mouths. They get their name from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. Sawfly larvae can be an important factor in the diet of a number of birds including partridge and black grouse.

Butterflies: from Jennyfields. Harrogate, Doug Simpson reports, “Had single Painted Lady, Holly Blue and male Brimstone butterflies in the garden on Sunday, 14 August.” All rare this summer and very welcome,

Holly Blue - Claire Yarborough

Holly Blue – Claire Yarborough

Claire Yarborough reckons, “We have had a bad year for butterflies, but had one interesting sighting. This bright blue butterfly was feeding on achillea in my garden this week. It would only pose for a photo with wings closed, but my ID book guided me towards holly blue. My first in the garden. Otherwise, we have seen plenty of whites, but nothing much else. Even the buddlea only attracted one peacock. When is the summer going to arrive!

Painted Lady - Jon Burge

Painted Lady – Jon Burge

Jon Burge, “Like others have noted, we have fewer butterflies than normal. Perhaps fallen apples etc of the season will attract more. We have two or three at a time red admirals, but just one at a time peacock, small tortoiseshell and painted lady. I provide a photo of the last, but unfortunately could not catch the more decorative underside.”

What butterflies have you seen?

Bilton Birds: Keith Wilkinson tells me, “I hope you have seen the Barn Owl that hunts morning and evening over Diamond Jubilee Wood at the back of you. She has raised/is raising two youngsters this year. Also the Tawny Owl in Bilton Beck Wood seems to have raised two this season. Have had reports that the Skylarks nested again but I can’t say I have seen it for myself.”

Wood Pigeon Squabs - Sue Turner

Woodpigeon Squabs – Sue Turner

Squabs: Sue Turner, writes, “Mummy Woodpigeon left the nest because we were doing some pruning in the front garden. I took advantage of taking a photo for everyone who says they’ve never seen a baby pigeon! As I’ve said before I don’t care for Woodpigeons but these are rather cute even though they are right above my front door.” Sorry Sue, but they really don’t look cute to my eye.

Hedgehogs: Delia Wells, “Woodlands Community Garden on Wetherby Road, saw the resident hedgehog, mid morning, 15 August, It was full grown, and not wary of people nearby.”
