August WILDLIFE

August 3, 2020September 8, 2020 | Rebecca Gibson

August is an intriguing time for wildlife. Although birds are relatively quiet at this time of year, insects are out in force. This month sees summer and autumn blending together and there is plenty to discover out in the countryside. So, here are some of my favourite British wildlife highlights during August.

This month, yellowhammers are one of the few birds still singing. They can be seen perching high up on gorse bushes as they fill the air with a charismatic phrase that many birders say sounds like “a little bit of bread and no cheese”.

Migratory British birds such as swifts and blackcaps start to make their way back south this month – swifts are particularly noisy flyers and soon the skies will be much quieter in their absence. Other migrants including swallows and house martins will stay around a little longer and usually depart around September.

Tawny owls may start calling in August, but this usually picks up in autumn and then throughout winter. It is during this time that young birds leave their parents and attempt to establish their own territories, using their calls to announce their presence. The well-known “twit twoo” call of a tawny owl is a combination of voices – the female calls “ke-wick” and the male answers “hoo-hoo-ooo”.

August is a good time to spot hares because farmland is starting to be harvested and crops are cut low to the ground. Keep an eye out for them darting along hedgerows or crouching low to the ground, looking remarkably like rusty stones.

Bats are actively feeding on the explosion of flying insects and badgers are starting to collect their bedding. Dry, warm weather can often mean there are fewer worms available and badgers may be drawn to gardens to drink from ponds.

Unlike red deer which rut in the autumn, roe deer have their breeding season from mid-July to mid-August. During this time a male – which is called a buck, not a stag – follows a female (doe) around and chases her in tight and continuous circles. This behaviour is known as ring-running, and when a ring is stamped into a permanent trail it may be used for future ruts.

August is also good for spotting insects. Dragonflies such as the common darter can be seen flying around ponds and other still bodies of water. They are also found far away from water as they rest on plants in patches of woodland.

This month, the second generation of many butterfly species are on the wing including comma, red admiral and painted lady. For those interested in butterflies, now is the time to contribute to The Big Butterfly Count. Launched in 2010, this UK-wide citizen science survey is running from the 17th July to the 9th August. It’s easy to take part – just choose a place to sit and record the butterfly species you see for fifteen minutes. As pollinators, butterflies are extremely beneficial for the health of the ecosystem but are currently facing severe declines, so the records collected during the count will provide valuable data for conservation projects and research.

A Charm of Bramblings

February 4, 2019February 7, 2021 | Rebecca Gibson

With the bitter cold of winter often come unexpected and welcome surprises. Two years ago, flocks of waxwings graced us with their presence as they passed through from Scandinavia. The following year, hawfinches could be seen crunching hard seeds with their formidable bills. In 2019, it seems to be bramblings that are turning heads as they gather en masse across the UK. While they have been known to breed in Scotland in previous years, this is very rare. However, bramblings often visit the UK during the winter months, with this year being no exception.

At a quick glance, bramblings could easily be mistaken for a male chaffinch; these birds are of the same size and have very similar colouration, if a little more diluted than our more common garden inhabitants. Both male and female bramblings have an attractive orange blush on their sides and a white belly. In summer, males have black markings on their head. Bramblings can be found in beech woodland and close to other wooded areas, often joining flocks of chaffinches to look for food. Like many finches, bramblings prefer seed, so providing a good seed mix could attract them into gardens. There are several collective nouns for finches, including a “charm”, “company” and “trembling”. I couldn’t find a specific term for a gathering of bramblings, but as the birds themselves are so charming to look at, a “charm” seems appropriate.

It is thought that the reason behind this year’s explosion of bramblings is beech mast, or fruit, that falls from the trees, dispersing seeds for the birds to eat. If the beech mast fails in European countries such as Scandinavia, species including bramblings will move south and west in vast flocks to find more food. While impressive gatherings of five hundred bramblings can currently be seen in areas of the UK, earlier in January there was a flock of around five million in Slovenia. This number of birds could seem difficult to comprehend, but even that pales in comparison to the flock seen in Switzerland in the winter of 1951, which was up to 70 million strong.

As with all winter visitors, the bramblings’ time here could be short. Despite the plummeting temperatures, wrap up warm and head outside to find some of these beautiful finches.

More to See, More to Zoo

Meeting the giraffes of Jacksonville

Last week I visited Jacksonville Zoo, which boasts “more to see, more to zoo”. And it certainly delivered, with a broad range of exhibits including some very special ones that I’d never seen before. A particularly unique exhibit was Wild Florida, a collection of species native to the state. I discovered just how big alligators are (which only confirmed my decision not to go anywhere near a river during my time here) and caught a glimpse of a manatee as it glided underwater. Manatees are the state marine mammal of Florida but threats such as collisions with boats, habitat loss and the devastating red tide have now made them endangered.

In response to these threats, Jacksonville Zoo is in the process of making the first manatee critical care centre in northeast Florida. This will allow more injured animals to be rescued and cared for, and minimise travel distance to other centres such as the ones in Miami, Tampa and Orlando. To make the experience as natural as possible for the manatees, they have a very large tank, which can only be viewed from one side. They are only seen occasionally when they swim close to the tank’s edge, giving them much needed privacy.

Elsewhere on the site was the Emerald Forest Aviary, where I met my new favourite bird: the roseate spoonbill. Native to Florida, this extraordinary wading bird is candy floss pink in colour and sports a magnificent bill that it waves from side to side underwater to sift through the mud. There was a group of them in the aviary, perched on branches overhanging a deep, dark pond. I positioned myself to put this dark pond behind a particular bird who had stood beside some very photogenic foliage. After just a little editorial tweaking, I was pleased with the dramatic result.

Although I always love seeing the star animals of the zoo, some of my best moments from the day were the wild individuals that had snuck in uninvited. As usual, I fell in love with some new lizards, including one that posed for me with an over-the-shoulder glance.

However, the most incredible moment came just before I left. I was wandering past the lions and admiring the wildflowers that were attracting all sorts of butterflies and dragonflies. Then, I saw something larger than an invertebrate zooming around and was thrilled to discover it was a hummingbird!

I fumbled to get my camera ready, and for a while took lots of blurry pictures of flowers. Eventually, I got used to the hummingbird’s pattern of flying and managed to capture the animal in frame. I stood watching it for ages, as usual receiving looks from passers-by wondering what I was so interested in. For me though, it was an amazing sight and one of those perfect surprises.

A Day at Sea

May 4, 2018 | Rebecca Gibson

Like almost every other visitor to the Isles of Scilly, I had my sights set on puffins during my stay, not to mention razorbill, guillemot and perhaps a seal or two. I’d planned on joining the afternoon Sea Safari around Annet, known as the bird sanctuary island, and the Western Rocks.

I wandered down to St Mary’s Quay to check it was going ahead and saw there was a trip to Annet in the morning too. I stood at the harbour and pondered what to do. The weather didn’t look promising – the looming clouds threatened to burst at any moment. So, somewhat recklessly, I bought a ticket for the morning trip and boarded the Sea King. As St Mary’s drifted slowly out of view, I hoped I’d made the right decision.

By the time we reached St Agnes the sun was doing its best to break through. As we headed out towards Annet, our guide pointed out the rock called the Cow, a smaller rock named the Calf beside it. When the tide came up, the Calf disappeared completely, only emphasising the fact that boatmen on Scilly needed their wits about them when navigating such challenging waters. Shags were perched on the Cow with wings held wide. The structure of their wings reduced buoyancy, which made it easier for the birds to chase fish underwater. As a result of this adaptation, however, their feathers were not truly water-repellent, so they needed to hold them up to dry them. Although, I doubted these shags would have much luck drying them in the current temperature. Perhaps it was for another reason; spread-wing postures aid digestion. Birds that adopt this position have low metabolic rates and high rates of heat loss. By positioning themselves with their backs to the sun, shags could increase the rate of thermoregulation, absorbing solar energy to increase their metabolic rate.

Lesser black-backed and great black-backed gulls wheeled overhead, mouths open as they wailed at us. I had my binoculars scanning the rocks and nearby surf for a glimpse of vibrant, toucan-like beaks and droopy, clown eyes. The skipper slowed the boat suddenly and I sat up straight – a sure sign he’d seen something. A pair of great northern divers cruised into view when a wave subsided – beautiful grey birds not yet in their summer plumage. The divers, as a group, were extremely glamorous, with sleek heads and slender necks and bills.

A while after our divers had swum further away, I suddenly found myself looking at my first puffins. Two of them, perhaps a breeding pair. Down the binoculars, all concept of scale was warped, and it was impossible to see how small they were – just 12 inches tall! After a few moments they took to the air and, flapping rather ungainly, they gathered enough momentum to carry them off across the water. I was thrilled.

Leaving Annet behind, we moved into choppier water, the boat swaying beneath us as it negotiated unsteady waves. I was reminded again of how wild and isolated Scilly was, and it was this seclusion that protected and enhanced its flora and fauna. It was an island paradise.

A razorbill – a member of the puffin family – flew into view, wings beating rapidly either side of a stout, monochrome body. It wheeled in a wide circle, zooming back around the boat and away again; a bird’s second glance, too quick to photograph.

Just before it was time to turn back, a vast herd of forty grey seals appeared, some sprawled across the rocks and others bobbing in the water, long dog-like noses pointing in our direction. There were a range of ages, with some of the seals still sporting very lightly coloured coats and juvenile, inquisitive expressions. They continued to gaze after us until the rocks obscured us from their view, and the skipper took us back to St Agnes.

Once we had all disembarked from the Sea King, it wasn’t long before the Spirit of St Agnes had taken its place, ready to take more eager birdwatchers out to sea. I decided that I rarely had the opportunity to go looking for puffins, so I bought a ticket and left dry land again, excited to be back out on open water.

Amongst the blue-green waves were the white outlines of gannets, looking like swans of the sea with their slender necks and stocky bodies. Britain’s largest seabird, with a formidable wingspan of six feet; not only did they have beautiful plumage and facial markings, but they were truly built for a life at sea. Gannets can dive into the ocean from heights of 40 metres, hitting the water at speeds of almost 60mph. To withstand the pressure of such a dive, gannets have “airbags” that protect their organs on impact. They also breathe through slits, situated where the upper mandible meets the head, which are covered by flaps of hard tissue that prevent water from entering them.

These gannets weren’t diving, but they were soaring low over the boat, providing beautiful photo opportunities. It was always a challenge trying to focus a fully extended 400mm lens on a rocking boat, but I kept the camera as steady as possible and followed the birds as they glided majestically overhead.

The last bird to make an appearance was a special one; the Manx shearwater. Belonging to the order Procellariiformes along with albatrosses, these birds can live for some sixty years. They only produce one egg a year, so are highly susceptible to predation by rats. To combat this, the Isles of Scilly Seabird Recovery Project was established to eradicate rats from St Agnes, as it was suspected that they could swim the reasonably short distance to Annet, where the Manx shearwater bred. The project was successful, St Agnes was declared rat-free and the birds are now breeding successfully. In 2015, a total of 28 Manxie chicks were seen to be fledging from St Agnes and Gugh. These birds only breed on Scilly and Lundy in the UK, emphasising the importance of protecting the Scillonian population.

Before long it was time to leave rugged Annet behind and return to (scarcely) populated St Agnes. Although we’d had Manxies and gannets on this trip, the puffins had eluded us. I spoke to the guide on the journey back and she said they didn’t like bright sunlight. As the clouds had shifted and it had turned into another beautiful day, the puffins were obviously finding shade elsewhere. Later, as I looked through my photos, I felt very fortunate to have gone down to the harbour earlier than planned.
