Out & About – Blackhouse Wood & Crews Hill

/ nrowberry / 1 Comment

Yesterday was a lovely sunny Sunday, so we thought we’d try and have a walk around the little nature reserve we’d failed to get to a few weeks ago – Blackhouse Wood and Crews Hill. Apparently yesterday was National Dawn Chorus Day, so a walk in the woods seemed like a nice idea to hear some bird song. With the Too Lazy ethos we were of course too late to really get the dawn chorus – the birds were doing more of a brunch chorus, by the time we got there, but it was lovely all the same.

Crews Hill signBlackhouse Wood and Crews Hill (which is also wooded) are both owned by Worcestershire Wildlife Trust and are joined to form one long thin area of semi-natural ancient woodland. The shape of the wood meant that for once, we were reasonably confident that we couldn’t possibly get lost!

The path ran pretty much straight through the wood, although it did undulate quite a bit thanks to old quarrying efforts years ago. We may not have quite been up in time for the dawn chorus, but for the first hour or so we didn’t see a soul. A lovely peaceful place to visit.

There were a lot of squirrels (all grey of course round here) scampering through the trees and lots of rustling of mice in the undergrowth.

The wood was full of bird song, although spotting the birds themselves wasn’t that easy. To start with there seemed to be loads of different birds singing, but they almost always turned out to be Blue Tits. I’d no idea Blue Tits had such a variety of songs!

Eventually of course we did manage to differentiate some other bird species. Chris has one of those apps that will identify bird songs for you and it picked up a song thrush although we didn’t actually see it. One of the few songs we can both recognise is the chiffchaff and they were also obliging enough to pose for photos, although this one didn’t look too happy about it.

Blackbirds, robins, goldfinches and of course woodpigeons could also be heard singing their socks off. The surprising highlight of the vocals though was an owl calling – neither of us have ever heard one calling in broad daylight like that. Sadly we didn’t see the owl, but we were really lucky to get a good view of a buzzard.

There were quite a few butterflies flitting about in the more open sunny patches; most as usual too quick to photograph apart from this Holly Blue and Speckled Wood.

Invertebrate highlight for me was spotting this tiny longhorn moth. As it fluttered down to land, it was its enormous antennae that caught my eye. The antennae are way longer than the moth’s body (hence the name) and it looks like it must take an extraordinary effort to keep them out of the way when flying.

We spent a very enjoyable couple of hours pottering around the wood; it’s nice to find another little gem of a reserve virtually on our doorstep.

Luring an Emperor

/ nrowberry / 8 Comments

Having missed most of last week’s sunny spell, (due to the considerable inconvenience of having to work for a living!) we headed out on Sunday to Hartlebury Common. Almost exactly 2 years ago we’d gone to Hartlebury in search of the Emperor Moth – with zero success that time. But this time we had a secret weapon – a pheromone lure!

Male emperor moths fly during the day looking for females. The females fly at night, but during the day they sit in the undergrowth wafting irresistible pheromones out to the males. The males pick up the scent with their feathered antennae and home in on the object of their desire. You can now buy pheromone lures that will fool the poor males into thinking you are a desirable female. This does feel a  bit like cheating and a bit mean to deceive the males this way. But since it was probably the only way we were going to see this beautiful moth, I’m afraid we went for it – although making sure we didn’t leave the pheromone lure out for too long to disrupt their normal behaviour.

So we wandered about for a bit before selecting what seemed a suitable spot to put the lure down. We’d barely got set up when the first male came hurtling over the gorse. It shot over the lure and landed on a gorse bush nearby, where he then stayed. They are big moths, so you’d think they’d be easy to spot, but it was surprisingly difficult even when we knew roughly where he’d landed. When we did find him, he was hanging on a twig with his underside towards us – so here’s one of our first photos.

They are really quite furry/hairy moths with very impressive big eye spots on the wings. The males’ antennae are very large and feathery to pick up the female pheromones. Not easy to focus on, but here’s my best effort.

Almost immediately a second male came bombing in towards the lure. This one however refused to settle. It seemed (not surprisingly) confused by the lure and flew around excitedly looking for a female. This blurry image is him circling the lure.

While he hovered around the lure looking for the female, I hovered around him trying to get a decent photo. As he didn’t settle, the best I managed of him was this flying shot. Not great, but at least you can see the lovely yellow underwings and all four peacock-like eyespots.

This second male eventually gave up and disappeared back into the gorse. The original male though eventually shifted position, so that we could now see his other side. So we finally got the classic Emperor moth shots we were looking for.

Having got the photos we wanted, we packed up to leave the males in peace to pursue genuine females. The moths weren’t the only animals with love on their minds though – these bloody-nosed beetles were clearly feeling spring in the air.

Hartlebury Common is very busy with birds. Last year we’d seen a small bird that was new to us and had identified it as either a Chiffchaff or a Willow Warbler. They are only distinguishable by their song and since we didn’t know to pay attention to this until it was too late, we couldn’t identify the bird. But this year we were definitely hearing Chiffchaffs all around us, so I’m reasonably confident that this one is a Chiffchaff (and probably the previous one was too).

The most obvious animals on the common were these cows with their resplendent horns. No idea of the breed, but they were pretty impressive. They appeared to be free to roam, so were presumably used to maintain the status quo of the vegetation.

So all in all we were very happy with our latest trip to Hartlebury. The pheromone lure worked a treat and the moths were every bit as stunning as we’d hoped. I’ve also bought the pheromone for the currant clearwing moth. These moths won’t come to regular moth traps, but like the emperors, the males are attracted to pheromones. So I’m hoping in the summer to try this out around our currant bushes on the allotment. Fingers crossed.
