Small mammal trapping results!

The small mammal-trapping event on Portway Hill a couple of weekends ago went really well despite us only catching one Wood Mouse on this occasion. Everyone who attended was given the opportunity to set a trap and a total of 12 Sherman traps and 3 Longworth traps were placed in the vegetation along the track through the old quarry and on the Wildlife Trust site. In each trap we placed a handful of sheep’s wool for bedding, and baited the traps with a mix of seed, cucumber, castors, lettuce and a small piece of cheese. The location of each trap was marked so that when we returned the next morning none of the traps were missed. They were then left in place overnight.

At 8am on the Sunday a group of 10 people showed up. Our initial disappointment at not catching anything in the first few traps turned to joy when a trap was retrieved containing a Wood Mouse in pristine condition. We carefully transferred the mouse into a small, transparent lidded bucket which was held up so that everyone could get a good look and take photographs. The mouse obliged by sitting there eating seed that had been transferred from the trap into the bucket with him. Although the bait was missing from two of the other traps on this occasion the trap-doors had failed to close.

After safely collecting up all of the traps we headed up the hillside in the direction of the radio masts to look for signs of mammal activity beneath some onduline roofing sheets that had been put down earlier in the year in the hope that any reptiles on the site might find refuge beneath them. No small mammals were detected beneath any of them but several little woven-grass nests constructed by voles were found.

Of the other wildlife we saw over the weekend the biggest surprise was a very late-in-the-season Speckled Wood butterfly, seen on the Saturday flying across the Wildlife Trust land. Buzzard, Kestrel and Sparrowhawk were seen overhead, and despite it being so late in the year, many of the hillside’s wild flowers were still in bloom, including Dog Rose, Yarrow, Burnet Saxifrage, Groundsel, Oxford Ragwort, Common Ragwort, Bush Vetch, Common Cat’s-ear, Tall Mouse-ear Hawkweed, Oxeye Daisy, Common Toadflax, Shepherd’s-purse, Smooth Sow-thistle, Red Campion, Red Clover, Black Knapweed and Weld. The exceptionally dry June and July followed by a mild autumn may have had something to do with this.

There has also been a change to the dates of the Wildlife Trust’s volunteer days in December – all the most up to date information is on our Events page so make sure you check there before heading out!

Here are a few photos from the mammal trapping event, with thanks to Andy Beaton for taking these.

Round-up of recent news from the hills!

Tom Hartland Smith, Senior Conservation Officer at the Wildlife Trust for Birmingham & the Black Country, recently wrote us this summary of the past few months’ events on the Rowley Hills:

If you have not managed to come along to any of the events and volunteer days over the last few months you will have missed out on an exciting look into what moth species we have on the hillside, of which the Chinese Character Cilix glaucata was a first spot for me, but all the moths on the hillside were new records for the site – how exciting! The glorious early morning bird walk for International Dawn Chorus day was a great success and we were rewarded with a lovely sunrise with spectacular views and delightful birdsong throughout. We also had another successful and delightful butterfly walk where we were greeted with a kaleidoscope of butterflies on a hot summer day. On one of the volunteer days we popped out some new reptile mats which we have positioned to gauge if there is a population of reptiles on the hillside (no joy yet but still checking).

During the regular volunteer days we have worked on opening up some of the public rights of way, re-installing PRoW way markers and tidying up the site when we can. We’ve also been monitoring the meadow in which we found Common Spotted Orchid, which is a first for the hillside, and spreading Harebell and Yellow Rattle seeds as well as introducing Alder and Purging Buckthorn to try and increase these food plants for the Brimstone butterfly.

A new replacement interpretation panel has been purchased and is ready to be installed on the cairn on one of the upcoming volunteer days. Myself and Mike Poulton are going to be meeting to sort out doing some small mammal trapping; information about this will be posted on the Friends of Rowley Hills website in due course. If you are interested in getting involved in the surveying of small mammals on the hillside, please email info@bbcwildlife.org.uk.

I hope you are all well and thank you all for making such a massive impact on a cracking site. I always look forward to the volunteer days and events on Portway Hill, as the hillside and people have so much to offer.

Join us for some volunteering next weekend!

We’ve got a big task to achieve on our next volunteering date, Saturday 20th October – why not come and join in? We need to clear all the mown grass off the wildflower meadow on Portway Hill – this will prevent it from rotting back into the meadow over the winter, helping to keep soil nutrient levels low to encourage a greater diversity of wildflowers. Meet on St Brades Close; ensure you are dressed appropriately for the forecast weather conditions, and wear sturdy footwear. You will need to bring along a packed lunch but tea, coffee and biscuits will be provided. No need to book, just turn up!

Here are a few photos from one of our recent volunteer days where we restored a public right of way marker that had been vandalised.

New photos in our Gallery!

We’ve just refreshed our main photo gallery with lots of lovely new photos, all taken by local photographer Andrew Cook who walks around the hills regularly with his camera! Here are a few to whet your appetite; to see them all, click here to visit our gallery.

Butterfly walk, Saturday 30th June

Don’t forget we have our annual butterfly walk in a few weeks’ time on Saturday 30th June, 10:00am -12:00am approx. Join us and the Wildlife Trust for Birmingham & the Black Country for a guided walk around the Rowley Hills. The flowers on the hillside should just about be at their best by this time and if the day is sunny we will see many species of butterflies, including Marbled White; Portway Hill is one of this species’ hotspots in Birmingham and the Black Country. Wear sturdy footwear and ensure you are dressed appropriately for the forecast weather conditions. Meet on St Brades Close at the junction with Tower Road at 9:50am. See you there!

2017 butterfly walks report

2017 has been a great year for butterflies on Rowley Hills and our two organised walks have been a great success, attracting 12 visitors in June for the first walk and 21 for the second walk in July.Saturday 24th June was sunny and butterflies were plentiful. Ringlets are the commonest butterfly on the hillside in June, and during the walk 149 individuals were counted. The Large Skipper is not large at all and only slightly bigger than its cousin, the Small Skipper. To get a good look at one is not always that easy, especially in bright sunshine when they seldom if ever land. It’s only when they do so that the brown markings are visible on their wings which satisfactorily distinguishes them from Small Skipper. During the walk a fleeting glimpse of a Painted Lady butterfly was a real bonus. This butterfly, whose ancestors started their migration northwards from Africa earlier in the year, several generations down the line, has finally arrived in Britain and it’s highly likely that this individual was only passing through on its way towards Scotland and beyond. This is the longest migration by any one species of butterfly and we felt very privileged to have seen one. For those interested in reading more about the incredible journey of the Painted Lady butterfly go to http://butterfly-conservation.org/5183-2342/painted-lady-migration-secrets-revealed.html and other similar websites.

The numbers of Marbled White on Rowley Hills had still to peak but nonetheless we still managed a count of 17. In some years hundreds can be seen fluttering above and in between grass tufts searching out mates, or in the case of females, randomly scattering eggs on to blades of grass as they go, across the whole of the hillside. Other butterflies and day-flying moths seen on this first walk were Red Admiral, Small Tortoiseshell, Speckled Wood, Meadow Brown, Six-spot Burnet, Latticed Heath and Burnet Companion.

In contrasting weather conditions, our second butterfly walk on Saturday 15th July started off overcast and cool with a blustery wind. This did not deter 21 people from turning out and as the morning passed conditions improved considerably, although we never actually saw any sunshine. When butterflies shelter from the wind and rain they get well down into the vegetation making finding them difficult. However, it wasn’t long before one sharp-eyed group member spotted our first butterfly of the day, a Small Skipper. This small, orange-brown butterfly looks very much like the Essex Skipper. Both are found on Rowley Hills and a close inspection of the underside of the antennae is necessary to separate the two. Good photographs of both can be found in books and on the internet for those interested in seeing the differences. It wasn’t long before we spotted the first Marbled White of the day, soon followed by a Ringlet, Meadow Brown, Gatekeeper, and Shaded Broad-bar. The distinctive black spots on a red background of the Six-spot Burnet is a warning to would-be predators that they are distasteful and should be avoided. The closely related Narrow-bordered Five-spot Burnet has very similar markings and both were seen during the walk.

Bung containing Six-belted Clearwing pheromones

We were fortunate to have Richard Southwell, a well-respected local lepidopterist with us today, and he had brought pheromones along with him to try to lure Six-belted Clearwing moths. This black and yellow moth has long been known from the Portway Hill site, but is rarely if ever seen. To look at, the adult moths are similar in appearance to wasps and hoverflies and this is possibly one reason why they go unnoticed. As we approached the land owned by the Wildlife Trust, Richard went on ahead of the rest of the party and hung the netted pheromone bung close to a patch of Bird’s-foot Trefoil, the moth’s food plant, in the hope of attracting moths to the lure by the time we got to him. Alas, on this occasion nothing came. Not to be deterred we continued our walk, heading upwards along the recently opened route through the old quarry, which brought us out at the top of Bury Hill Park. As we walked, Bullfinch, Goldfinch and Speckled Wood butterflies were noted.

The views towards Birmingham and beyond from the top of the park are quite stunning, and in the unmown grassland, patches of Harebells were now flowering. Bury Hill Park grassland probably has the largest population of harebells in the whole of the Black Country and it was reassuring to see that the council had left the grass uncut giving the harebells the opportunity to flower and set seed.

Moving on from here we followed the track along the rear of the gardens in St Brades Close passing several webs of the unmistakeable Labyrinth spider Agelena labyrinthica. The webs of this spider are constructed in south-facing hedgerows from July to September and are sometimes so thickly woven that they appear white in colour. At the one end is a funnel shaped retreat, and further down the funnel there is a labyrinth of tunnels which gives this spider its name. Hidden deep down in the centre is the egg sac containing the developing young. The females remain with the young until they are ready to leave the web and in the event of the mother dying before the spiderlings are ready to leave the web, the young will eat their mother!

Even in the driest of summers the ground at the rear of the gardens in St Brades Close is always wet. Rushes, sedges, Tufted Hair-grass, Great Willowherb and Reed Canary-grass thrive in these conditions, and as we passed our eyes were drawn to the numerous little whitish-coloured cases attached to almost every flower head on the Compact Rush. These were later identified as Case Bearer moth larvae Coleophora sp. This is a large group of similar-looking micro-moths whose larvae feed on flowers and seeds of various plants from within protective silken cases. 

A little further on we arrived at the only known patch of Sneezewort on Portway Hill and nearby, a large Roesell’s Bush-cricket was spotted in the grassland.

Making our way back towards the start point a second attempt with the pheromones this time proved successful and within less than two minutes of positioning the bung near to a patch of Bird’s-foot Trefoil, several male Six-belted Clearwing moths had come to investigate. It was difficult to determine just how many individual moths there were as they fly so quickly but we estimated that there were at least 12. Flushed with success the pheromones were put down in two other spots where Common Bird’s-foot Trefoil was growing, and on each occasion clearwing moths appeared in no time at all. A great finale to another interesting walk.
