A Bad Case of Songthrush

The Song Thrush: one of Britain’s most charming and decorous songbirds. Dressed tastefully in brown, black and gold, it hops about in our pasture tweaking at this or that worm, bashing snails against rocks or cocking its head to watch passers-by.

One of the most frequently asked questions on my walks is “why do you have so many thrushes?” Why indeed. I have often asked myself the same question at 3:05am, when they all erupt into song right outside my window. I have a high tolerance for birds; but at that time in the morning, good humour is thin on the ground.

Even more annoying is their interval – usually somewhere between 4:00-5:00am – which lulls the human sleeper into a false sense of tranquillity. At 6:00am they all strike up again, shrieking like car alarms. This uncharitable behaviour would try the patience of even the most virtuous bird lover.

So why do we have so many Song Thrushes on Glengorm? To answer that, we must turn the question on its head: why might there be fewer of them elsewhere? Song Thrushes are a Red Listed species in Britain – their decline seems to be linked to the way our landscape is used.

Intensive arable agriculture doesn’t suit thrushes. They prefer a mixed farmland environment, and preferably, one that includes permanent cattle pasture. Such pastures are rich in manure and its associated insect life; ideal foraging habitat for the Song Thrush. They also like hedgerows, woodland, wet flushes and gardens – all of which provide opportunities for nesting and feeding on insects and fruits.

Most Song Thrushes don’t live long [average 4yrs] but they can make up to five breeding attempts per season when the getting is good. Song thrushes produce fewer broods per season in intensively farmed areas – to such a marked extent, that they can no longer recruit enough young birds to keep the local population topped up.

Thankfully there is evidence that the overall decline is stabilising, and there has been a partial recovery in the last 10yrs. With luck, thrushes will be depriving me of sleep for many years to come.

Owl Save You!

To people who work in outdoor jobs, boxes can be scary things. They are carried anxiously towards you, held at arm length to avoid jiggling the contents.  The faces bobbing above the box are filled with nervous excitement and concern – the mouth a pale “O” of part-formed accounts and explanations. Birds seem to cop for more box journeys than other taxa. Normally, the lid is lifted to reveal a fallen nestling or unfortunate adult that has struck a pane of glass. Sometimes, it is a rabbit hit by a car or a hedgehog that rose too early from its winter sleep.

On this occasion it was owls. My surprise was absolute. They looked like two very mouldy grapefruits; completely spherical and covered in flaky grey fuzz. They were rather wet – the smaller of the two also sported a layer of mud over its growing feathers. The owls did not look pleased to see me. At the back of their black eyes, a disapproving blue light swam. The largest of the pair clicked its beak. The younger owl seemed cold and disinterested.

It is not unusual to find tawny owlets on the ground – indeed, like many other species of bird they will depart the nest before they are fully qualified aeronauts. They often fall as they clamber flightless through the canopy. In the majority of situations, it is best to leave them where they are – or apply the same common sense that you would use with an ordinary garden bird. Tawny owlets are normally quite capable of getting up off the ground to safety. This pair was found at the edge of a mature plantation; they must have struggled to climb the smooth, tall trees in time to escape Mull’s infamous spring weather. I lifted each one to check its condition. They were chilled and lethargic, but otherwise well grown.

Once the owls had dried and been gently warmed, they peered myopically out of my laundry basket. Their posture had changed from a moribund slump to something more dignified. They were comically hostile; but not too proud to scoff the shreds of rabbit hide and mice that I dangled enticingly above their beaks. These latter would be swallowed whole right down to the tail, which then protruded from the corner of their gape like a Winston Churchill cigar.

Sadly, the smallest owl died on the second night. He didn’t seem to be digesting his meals like the other, and went downhill very quickly in the small hours. Finding another owl for the second chick to be reared with was of paramount importance. It is not good practice to rear young birds in isolation, since they become too familiar with their keeper and then cannot be released.

Happily, my friend Sue provided the perfect solution. The owlet is now safely installed in a large aviary at Corrie Meadows, with an adult tawny to reinforce his avian identity. Fingers crossed he will be gracing our night skies in a few weeks time!

A Whole Lot of Otter

Recently, I experienced a desire to know more about otters. For reasons unknown, their whiskery faces had bubbled up to a more prominent pool in my consciousness. Thumbing the instructions for a new trail cam and staring into the middle distance, I felt compelled to investigate.

Encounters with these animals have an arbitrary quality. I have never pursued them; simply enjoyed those occasions when our paths cross.  As such, otters have seemed mysterious to me. Capricious, even. So armed with freshly honed field skills, I packed my lunchbox and took off for the coast. The weather was fine and fair – the first bright morning following many days of rain.

I don’t generally like to fly my own kite (!) but I have become something of a dropping connoisseur. What was once a passing interest has pupated into an unusual and eccentric obsession. For this we can thank the Aigas Field Centre.

Otters use their spraints as a means of communication, so they are normally deposited in choice locations where the scent will carry and not be erased by the tide. Often, these parcels of fishy fertiliser cause local plants to thrive; sprainting sites will look unseasonably green during the cool months.

Fresh otter poo is dark and crispy, with a sweet musk smell that goes easy on the nose [you heard it here first]. Consistency and composition will vary based on what your otter has been eating. The sometimes-present shards of crab and lobster shell can induce a light clenching in the muscles of the casual observer; try not to let that put you off. If you’re really keen, there’s always anal mucous to look out for too…

I have spent a lot of time looking around our coastline. Once I learned to see, a hidden network of neat grass paths, soft couches among dry vegetation and feeding pools filled with the bloated skins of toads popped up like a picture book. I only had to half close my eyes to imagine a whisky-brown back bounding between the thrift, or turn the page to see it snoozing under a downy of sea campion.

Some days later I went back to check the trail cam. The first video started with a blank screen of reflected infrared and a series of peculiar rustling sounds. Confused, I flicked to the next file.

A bristle of delicate whiskers slid out of the whiteness, followed by the outline of spiky-wet fur and a glimpse of beetle black eyes. A five-toed foot slapped irritably at the camera housing.

The otter was practically glued to the lens.

The stage curtain had lifted, but the taste of victory was bittersweet. I had pried into the life of something wild, and in doing so, caused a piece of its glamour to fall away. Its haunts and habits were exposed, its cover blown. Unwittingly I had become a keeper of secrets.

After all, nothing makes a creature more vulnerable than a GPS map of where it goes to the toilet.

Mammal Handling

The Bank Vole rotated slowly in its polythene bag. I wasn’t confident that I could catch it.

As it regarded each member of our group through ink-drop eyes, I wondered darkly what it was capable of.

Alicia – staff naturalist at the Aigas Field Centre – made it all look easy. She tipped the bag and the vole scuttled into a corner. Once there, she reached up from underneath to gently restrain its head; using the other hand to scruff it expertly.

Safely caught by the loose skin on its nape, the little creature was whisked out of the bag and presented to us in mid air. Its tiny pink feet paddled ineffectively. Realising that there was no chance of escape, a look of resignation settled and it allowed us to measure its ears.

Other members of the group, nervously clutching bags of voles, got stuck in. I was heartened. Success was everywhere.

We had set the traps the previous evening; baiting them with grain [plus some warm bedding] and hiding them between tussocks of grass and heather. There were three different sorts – some of metal and some of plastic.

Retracing our route at dawn, only the final batch of traps had been successful. Each was opened in a strong plastic sack to allow the occupants to be captured. We were collecting bio-metric data for submission to the Mammal Society.

The bank voles were quite amenable, and after a brief struggle, allowed themselves to be carefully transferred between group members for handling practice.

Measurements were taken. Data was recorded. Voles were admired.

The Woodmouse, however, proved to be an entirely different animal.

Woodmice are very beautiful. They are larger and more handsome than the familiar House Mouse. Rather than being mousy-grey all over, their coat has the rich orange hue of autumn leaves. Their chin and underside is a crisp, clean white; with an elegant pinkish-brown tail, every bit as long as their body. Their faces are pointy and alert -being framed by a spray of twitchety brown whiskers.

They are also quite neurotic – which, I suppose, is what happens when everyone else wants to eat you.

My woodmouse did not look pleased. It’s beetle-bright eyes bulged; every hair on its body seemed to thrum with latent energy and adrenaline. Swallowing anxiously, I reached into the plastic sack. The woodmouse made a terrific jump, fully extending its spring-loaded hind legs, and almost vanished up my sleeve. Hastily I crunched the plastic sack shut and withdrew my arm. I tried once again to restrain it in a corner from underneath.

Reaching in for a second time, I managed to finger the little pocket of loose skin behind its head. Holding as firmly as I dared, I elevated the mouse and brought it into the open.

It squirmed like an eel. Alarmingly, the mouse’s body didn’t seem to be attached to the inside of its skin, so it was able to rotate freely within its furry coat. I struggled manfully to maintain a grip, but failed.

The mouse scrabbled onto the cuff of my jacket, before plopping down onto my boot and leaving a rooster trail of displaced pine needles as it shot immediately into the brash.

I’m just grateful that it didn’t bite me on its way out…
