Beginning to settle in

The past week has seen me working on a variety of tasks at work – including (but definitely not limited to) making new information displays for the visitor centre, writing Facebook posts for the Trust, rearranging some of the interpretation at the centre, starting research into a report that I will be writing and of course, the usual running of the visitor centre for the long weekend (Fri-Mon).

I say “the usual”, but each day is different! I see different species, particularly if I’ve been moth trapping or decide to go out with a sweep net (tomorrow’s plan), listen to a variety of programs as I work if the centre is very quiet (mostly Radio 4 – Just A Minute, Ramblings, Inside Science and Costing The Earth), and every time someone walks into the centre, I know that something new will happen. I have had such a variety of conversations this week – the politics of conservation, the process of CRB checks and the Scouting movement, the bizarre forms of ladybird larvae, and of course, how cool moths are! Inevitably, I meet at least one new dog every day which I absolutely love.

So a round-up of some of this week’s wildlife. Not many butterflies as the summer draws to a close, but I did see a new favourite of mine – the Small Copper Butterfly. And I took a photo of it that is now one of my favourite butterfly photos that I’ve ever taken. It was resting on the wall of the Visitors Centre above my head, and I had to lean into the wall and look up to get the photo. I feel like it’s thinking “What are you doing?!” There were also moths about of course, including some new ones for me such as the Autumnal Rustic, Hedge Rustic and Rosy Rustic (I sense a theme …), and the ever-fabulous Canary-shouldered Thorn.

I also found a dead bee, which made me sad. But I took the opportunity to study it closely, and saw that what I believe is it’s tongue sticking out the mouth. There are three parts to the tongue it seems. Very interesting, and now I want to look into bee anatomy.

Three-part tongue?!

Towards the end of the week, I went to a local theatre production by Mid-Powys Youth Theatre at the Willow Globe (open air theatre- my favourite!). They were performing Humans On Trial – An Ecological Fable, and they were fantastic! The premise is that humans are trial for their actions against animals. With witnesses, a judge, a prosecution lawyer and a defence lawyer, the crimes of the accused are laid forth and debated. It’s a great play and very thought-provoking. If you get the opportunity to see it, do so!

Next week should bring even more variety as I continue moth trapping, go out with the sweep net, potentially assist on a bat survey, sort through some of the interpretation at the centre (including skulls!) and attempt some wildflower identification.

UK Species Profile: Fallow Deer, as voted winner!

If you took part in the species profile poll last month, you may have seen that the winner was the Fallow Deer whose scientific name I absolutely love – Dama dama. I was fortunate enough to work within, and live on the edge of, an amazing country park that was home to three different species of deer – Fallow, Red and a Chinese species, the Pere David’s (listed as Extinct in the Wild, a very interesting species to read about, but not now).

The Fallow Deer are such a recognisable deer species – well, when they have their antlers … and if they have the spotted coat, otherwise there are possibilities of confusion if you’ve not read up on your deer identification.

If you’re new to deer identification, I’ll take you through the main features.

  • Antlers (males aka bucks only) – unique for a British species, they are palmate with a flattened section, rather than the typical branched antlers that you’d associate with deer (i.e. think of Red Deer and their antlers).

  • Coat – the most common and associated pattern is the tan colour with white spots and three colours (tan, pale tan and then white on the belly), but other varieties include a paler version (Menil), black, white (these are not actually albinos, it’s a true coat colouration).

  • Bum (rump) – from the back, this deer has got a white backside which is bordered with black, and black down the tail so that a ‘M’ is formed.

Fallow Deer are actually native to south-west Asia, but were introduced to Britain by the Normans around 1100AD and it is now the most common deer here. It is now a naturalised species, and not considered as an invasive threat (basically, it’s been here so long that we’re just like: yeh, you guys are ok here).

These deer stand at a decent height – between 50-120cm, which is a measurement of their shoulder height (i.e. not the neck, head and antlers!). As mentioned previously, they have unique antlers in the UK, which are called palmate (compared to the usual branched). The bucks grow their antlers over summer to reach full growth by autumn, when they are used as weapons during the rut (fighting between the males for the females). Whilst growing, they are covered in a lovely furry skin called velvet, which dries and peels off in autumn. The antlers are then shed in spring, where they may then be gnawed and nibbled on by other animals, and the deer themselves, as they provide an excellent source of calcium. Younger males take a few years til they develop a fully grown set of antlers.

In terms of behaviour, the rutting is probably the most interesting to watch. Occurring in October, when the bucks are full of testosterone and the does (females) are available for the taking. There is plenty of fighting as the bucks defend territory and the does they’ve attracted. The bucks groan loudly and parallel walk to each other, sizing each other up, after which they may then fight.

The behaviour varies slightly with fallow deer depending on both the environment and the population density. Individual bucks may defend a particular area (rutting stand) which is attractive to the does, so one buck has a harem of females. Or the bucks may seek out receptive does where they are in low density areas. High buck densities may result in leks where a couple of bucks share the harem.

Females are polyoestrous – this means that if they do not conceive / become impregnated when they first come into season, they will come into season repeatedly. This means that fawns will occasionally be born as late as September (compared to the usual June-July). After a gestation (pregnancy) period of 234 days, the fawns are born in June-July, and are weaned by the next rut.

I don’t want to go on and on about Fallow Deer so I shall begin to round up the information. I had a fab time during my year in the country park (FYI: Margam Country Park in south Wales, very beautiful place). Mostly because I was generally loving my placement with the Field Studies Council, but I was also seeing deer everyday and that’s always going to cheer someone up (as well as the friendly ginger piglets on the farm, oh so cute!). One of my favourite parts of the week was a nature walk with KS2 school groups – we would always see the deer and it was great to see the kids’ reactions to such beautiful animals, and to help them learn more about the animals.

Some other interesting facts I’ve come across:

  • They can get quite old: 8-10 years (though 16 years can be reached by the females).
  • This deer species is often considered a serious pest, usually in commercial forestry, and are also a common cause of road accidents. They are often culled in some areas (particularly southern Britain) and their meat is sold for consumption (venison).
  • The sexes normally live separately for most of the year, only coming together for the breeding season.
  • Young males who are yearlings are called prickets.
  • It seems that I only have decent photos of the male deer!

Moth Solo – A new adventure, the battery strikes back and return of the ermine.

I was first introduced to moth trapping in 2012 during my placement year with the Field Studies Council at Margam Discovery Centre (South Wales) when one of the tutors fixed the moth trap there and set it out. The species that sticks most in my mind was the Drinker moth, I was particularly impressed by its antennae. This year I took a short course in invertebrates, as one of a number of extra-curricular ecology modules that I took alongside my third year at university. It was run by Dr. Phil Ward – an expert on invertebrates and a county recorder in Radnorshire. He introduced different types of moth traps, and over two nights we caught a variety of different moths – including a gorgeous Poplar Hawkmoth (L.populi).

A weekend in mid-June provided a good opportunity. I had the time, the need and the space. I was house-sitting for a family friend at their Bed and Breakfast / self-catered Farmhouse in mid Wales – Glanoer in Bettws, Llandrindod Wells, and they were keen for me to do some casual ecology surveys. I’d previously found otter spraint at the stream running through the smallholding, which surprised and amazed them. This time I wanted to do something that I’d been hoping to do for a long time: moth trapping.

I was keen to get going on some solo moth trapping, but was lacking something vital – some equipment. But the moth county recorders of Radnorshire came to the rescue and were kind enough to lend me two traps for the weekend, as well as discuss the best spots to place the traps. And so, I was ready to go.

The first night commenced, and I was doubtful. It was raining, windy and cold. Not a good start. I awoke bright and early, keen to check the traps but worried I hadn’t caught anything. My fears were unfounded. True, it was a low number, but I was thrilled! The two traps revealed 8 moths. Including three Hawkmoths! Two Poplars (L.populi) and a new one for me, the Elephant Hawkmoth (D.elpenor, photo below), which was absolutely stunning.

And so to the second night, the dreary weather was repeated though it was slightly less windy. However, only one trap this time. Although the light had been working on one I went to bed, the battery had evidently died not long after. Perhaps in retaliation for being stuck out in the rain all night?

Again, I was not disappointed. Another 6 moths! No Hawkmoths this time, but some gorgeous moths nonetheless. One thing that struck me was the White Ermine moth (S.lubricipeda, photo below). I’d caught one on both nights – not the same one, I’d kept the first one until after the second night to ensure that. What intrigued me was that the second individual was in exactly the same spot on the moth trap as the previous one. Was it that the spot was preferred by that species? Had the first individual left a mark there of some sort, perhaps a pheromone or scent? Very mysterious – if you know of a potential answer, I would be very interested to hear.

To finish off, before I end up rambling about moths for ages, my aunt was delighted to have identified moths to add to her smallholding species list, and was astonished by some of them – particularly the Hawkmoths and the White Ermine. The county recorders were pleased, this was the first moth recording in that area for at least thirty years, if not more. Although I’d not caught any species of special excitement, they were very glad to have recordings at all and are keen for me to do more trapping when I’m next visiting. Of course, I will happily oblige. Lastly, I’m satisfied that I’ve done my first solo moth trapping and can’t wait to do more!

NB: If you’re interested, the identification book that I used was The Concise Guide to Macro Moths of Great Britain and Ireland by Martin Townsend and Paul Waring, published by British Wildlife Publishing, and identifications were confirmed by the county recorders.

PS: I know it doesn’t fit exactly but I am rather proud of my post title here, and feeling slightly geeky.
