Britain’s Mammals - A Review

On my desk for review today is a new Princeton field guide, a book which doesn’t feature birds but one that will be sought after by almost 100% of bird watchers. The book is the much awaited Britain's Mammals: A Field Guide to the Mammals of Britain and Ireland from Princeton Press. This is the latest in the series of best-selling WILDGuides. 

The authors of Britain’s Mammals are Dominic Couzens, Andy Swash, Robert Still, & Jon Dunn. Andy Swash and Robert Still were two of the authors of the hugely successful “Britain’s Birds”, first published in late 2016, a book which found its way into many a birders' library. This latest book is a companion to the bird guide and shares not only one of the authors, but also looks and feels the same as soon as the first page is turned. 

Britain's Mammals

Skipping introductory pages to books is a bad habit of mine, but on this occasion I found myself immersed in the Introduction to Britain’s Mammals. It really is essential reading by firstly reminding us that in comparison to birding, mammal watching is a minority interest with much to be discovered by those willing to devote time and energy. 

The Introduction explains in just a few succinct pages the life-cycle and biology of mammals together with a very useful explanation and diagrammatic display of the names and scientific classification of Mammalia. A handy text and photographic overview of the types of British mammals reminds the reader that in comparison to the comparatively easy pursuit of birding, the study of mammals requires different techniques. A potential mammal watcher must exploit various times of both day and night and often use different equipment and methods to find and photograph their elusive quarry.

Part of the Introduction, the History of Britain’s Mammals, describes how getting close to wild animals takes a great deal of concentration and patience to achieve any sort of result; watching mammals is infinitely more difficult than birding. There is a timely explanation of why. For seven centuries or more persecution and exploitation of both land and marine mammals was rife, with many species becoming extinct or their numbers seriously reduced. No wonder then that history has taught mammals how to avoid homo sapiens, their most deadly and persistent predator. 

I guess I suffer from many misconceptions about British mammals, the main one, borne out by a glance at the book’s Contents page, is just how many mammal species can be seen in the British Isles. It is easy to forget that the UK and Ireland terrestrial mammals like squirrels, voles, mice shrews, moles, hedgehogs, rabbit, hares, carnivores and deer are in the minority. Bats and marine mammals form the largest groups of British mammals, reflected in the 70 pages devoted to 30 species of bats and over 40 pages featuring 37 species of marine mammals – seals and cetaceans.

The field guide element of Britain’s Mammals has handy and up-to-date distribution maps on the species' page together with illustrations which denote both the status and size of the animal. A typical page contains tips and information on where to look for a particular animal, its habitat, habits, food, breeding behaviour and population status. Very often there is information and helpful advice on the tracks and signs that may give away the animal’s location and/or its identification.

There are seven pages devoted to illustrating animal tracks. The publishers even provides a ruler in the inside book cover for the reader to measure tracks they find and then compare with scale bars depicted at the illustrations on each relevant page at p46-52. What a simple but innovative idea from the authors to make this a fully interactive field guide.

I must make special mention of the photographs in Britain’s Mammals. They are almost without exception truly stunning given the difficulties of in the first place even seeing mammals in the British countryside. In particular, the photographs of bats, both in flight and at rest, are simply superb, as are the pictures of mice and shrews. These are animals which are rarely glimpsed by everyday field workers who spend many hours in the great outdoors. I can only marvel at the time, skill, effort and dedication devoted to taking these images.

In summary. The winning WILDGuide formula continues throughout this wide-ranging and attractively designed field guide that follows in the major footsteps of Britain’s Birds. There’s a fully photographic experience and high quality information from its approximately 500 colour photos and 325 pages. 

Britain’s Mammals is a book for simple enjoyment as well as for learning and I heartily recommend it to readers of Another Bird Blog. It is available now from the usual sources at $29.95 or £17.95 and is something of a bargain.

Friday Flights

Friday began with a Barn Owl flying across Head Dyke Lane a hundred yards or more in front of the car. By the time I reached the spot the owl was nowhere to be seen so I didn’t hang about. There should be plenty of Barn Owl sightings soon. 

At Wrampool there was a Kestrel hanging about the set aside field together with a handful of Linnets and Tree Sparrows. Maybe the Kestrel was hoping to grab an unwary bird when it sped low across the crop a couple of times before returning to its base of the roadside trees. The Kestrel was an adult female but as mentioned recently, Kestrels seem scarce this year and this autumn I have yet to see a juvenile. 

At Conder Pool I found both Avocets on the pool, the adult and a still unfledged juvenile. A number of times the adult flew off to the creeks to feed and left the youngster on the pool margins where it continued to feed alone. Soon it will be ready for lift-off into adulthood. 

Avocet

Otherwise there was little change of both species and counts from recent visits with 140+ Lapwing, 35 Redshank, 5 Common Sandpiper, 4 Oystercatcher, 20+ Curlew, 6 Little Grebe, 2 Wigeon, 2 Little Egret, 1 Grey Heron, 1 Goosander, 6 Pied Wagtail, 12 Linnet and 2 Stock Dove. 

Little Egret

A notable absentee today was Greenshank, with not a one found, whereas a single juvenile Shelduck was the first I had seen for many a long week. 

Shelduck

 

The Shelduck, a bird of sheltered estuaries or tidal mudflats breeds in Great Britain & Ireland and has a well-defined moult migration. Most Shelduck fly east between late July and early September and head for the Helgoland Bight in the Waddensea, where they join birds from Scandinavia and the Baltic. Others remain and moult on North Sea estuaries, such as the Firth of Forth and the Wash. As a result of this migration there are very few of them around this part of Lancashire during August. In stark contrast to this situation, come mid-winter there are many hundreds along our local shores and estuaries. 

Over Glasson village there was a concentration of 30+ noisy and excitable Swifts but otherwise a handful of Swallows over the marina/yacht basin.

Things were pretty quiet so I made my way to Knott End again. I’ve been there a couple of times this week to watch the tide in and look out for terns. 

It’s a good time of year to see Sandwich Terns and Common/Arctic Terns when they roost on the flat sands at times of high tides, taking a rest from feeding in the near Irish Sea. The Sarnies  originate from a mix of locations in Scotland, Wales and Cumbria with their normal peak migration in mid-August when in some years up to a couple of hundred may be seen at Knott End, a favoured site. 

Before the terns began to appear I walked up river and counted 2 Grey Heron, 2 Little Egret, 300+ Oystercatchers , 1 Redshank, 140 Dunlin and 5 Pied Wagtails. The Sandwich Terns obviously peaked earlier in the week because I counted less than a dozen today compared to 150+ at the beginning of the week and then 49 on Wednesday. On each occasion I noted approximately 25% of juveniles, black& brown mottled birds of the year. 

Sandwich Terns

In the UK as a whole Sandwich Terns have shown a decline in productivity since 2000 when they fledged a record number of chicks. In the 14 years prior to 2000 it could be argued that productivity showed no clear trend, although in 1991 and between 1997 and 1999 it was particularly low. Few chicks fledged in these years due to bad weather, predation and disturbance by a variety of mammals and gulls, with food shortage implicated at only one colony. Predation on eggs and chicks by foxes Vulpes vulpes is probably the most prevalent factor determining productivity, and abandonment of a colony is often the result of predation. Nature reserve managers use electric fences to exclude foxes, which are not always successful. As Sandwich Terns nest on low-lying ground close to the tide edge, their nests are vulnerable to tidal inundation.

Further to Monday’s post on Another Bird Blog, a review of "Britain's Birds", I hear that demand for the book has already outstripped supply and that delivery times may have to be lengthened. Just as well those blog readers were amongst the first to read my recommendation to buy and hopefully they won’t have to wait too long for their own copy of this fine field guide.

Overground And Underground

I set off this morning just in time to see a spectacular sunrise appear over Cockerham. Our west coast of Lancashire has remarkable sunsets also but there’s something very special about the light of a new day dawning over misty fields. 

A Cockerham Dawn

As usual I was on my way to Conder Green where with luck and more than a little perseverance it is possible to see a good selection of birds. I wouldn’t be disappointed, especially as the regular Barn Owl was doing the rounds of the road and the marsh at a steady 20 or so mph in trying to evade my camera and the odd vehicle that came by, even at 0600. 

Barn Owl

The usual birds graced the pool and the nearby creeks with waders at 90+ Lapwings, 30+ Redshank, 14 Oystercatcher, 5 Common Sandpiper, 2 Avocet, 2 Greenshank and 1 Dunlin. In the egret and heron department were the customary 3 Little Egret and a single Grey Heron, the numbers of both yet to show any real increase this autumn. 

Common Sandpiper

Tufted Duck have been present all spring and summer in fours, fives and sixes with the appearance today of a single brood of tiny young. With just three in tow the female has considerably less than the 10 or so ducklings more typical of the species immediately after nesting. The female flew in alone from over the canal calling to the youngsters as she landed that the coast was clear. The chicks quickly left  their hiding place in bankside vegetation and joined mum on the water. 

Tufted Duck

Other wildfowl seen - 6 Little Grebe, 2 Wigeon, 1 Teal and 1 Goosander. Four Swift flew around briefly and I suspect they were migrants as overall Swift numbers are down in the past week or two. How soon does summer change to autumn.

A quick look at Glasson Dock revealed several Coot, 6 Tufted Duck, a single Great Crested Grebe, and 2 Common Terns fishing both the dock and the yacht basin. 

I drove back over Stalmine Moss where I followed the song of a Yellowhammer, an increasingly scarce farmland bird which has reached almost celebrity status with local birders. A yellow male was singing from a fence post with a browner bird flying off as I approached the spot.

I stopped to watch a pair of Buzzard circling overhead but then noticed what looked like a small animal immobile in the centre of the carriageway. It was a very fresh but also very dead Mole. 

Mole - Talpa europaea

The Mole Talpa europaea is one of the most common and widespread of mammals in the UK, but because it spends most of its life in the tunnels which it digs, it is rarely seen. For most people, it is the familiar sight of molehills of soil in woods and fields and even on lawns which is their only experience of these secretive animals. 

Moles are only about 15cm long, but have stout forearms and broad front paws with strong claws which give the animal its ability to tunnel so effectively underground. Their bodies are roughly cylindrical with no neck and a pointed nose, and they are covered in thick, dark fur. 

A Mole’s diet mainly consists of earthworms, but they also feed on beetles and other insects, even baby mice and occasionally shrews if they come upon them while on the surface. A mole needs to eat the equivalent of its own bodyweight each day. In autumn they make a store of hundreds of earthworms to last them through the winter. The worms are usually chewed off at the front end so they cannot crawl away, but remain alive and so provide fresh food for several months. 

Moles are not blind, as most people believe. They do have eyes and internal ears, but these are very small to prevent them being clogged up and damaged during tunnelling. Although they can see, the mole’s eyesight is poor, with no ability to detect colours, just light from dark and movement. However, the mole has a special weapon to help it find other animals underground - an area of bare pink skin on the snout covered in tiny pimples that detect movement and the scents of prey and other moles. 

Large molehills mark the position of a nest, sometimes known as a “castle”. A line of small molehills marks the direction of a deep tunnel while a continuous line of earth marks a very shallow tunnel. Moles are considered as pests where they damage lawns and fields that farmers like to see flat. Many methods are used to try to eradicate them, often with only limited success.
