CABOT TOWER BIRD STUDY GROUP
The Cabot Tower Bird Study Group is a visible migration study and raptor watch that meets *weekly at the top of Cabot Tower during the spring and autumn migration periods, to collectively scan the skies over Bristol for passage migrants and birds of prey.
It is an extension of a wider UK urban migration study, that began in London at the top of Tower 42 in the autumn of 2009. Data collected will be collated with the established Tower 42 Bird Study Group , conceived and run by David Lindo (The Urban Birder), which regularly contributes valuable migration data to the BTO via BirdTrack.
The aim of the initial sessions during the late autumn of 2011 will be to monitor numbers of passage migrants and arriving winter visitors, to monitor Bristol’s urban peregrine and buzzard population and to look out for passing raptors rarer to Bristol (eg. red kite / osprey).
The group has permission to access Cabot Tower before sunrise (when public access is allowed) and is open to anyone with an interest in birds or wildlife who would like to be involved.

This autumn, we will initially only have space for c.10 people in the group, including birding / photographic equipment. Numbers may be re-evaluated before spring 2012.
For more information, please comment below and I will add your email to the mailing list.
*frequency of watches may be increased during conditions propitious for migration.
THE IMPORTANCE OF URBAN WILDLIFE STUDY
Urban wildlife studies are becoming increasingly important. Around 90% of the UK population now live in urban centres and that figure is on the increase. With the development and spread of towns and cities, there is an increasing amount of urban habitat, which often results in decreased biodiversity and the suffering of native flora and fauna, unable to adapt to a rapidly changing environment.
Understanding how wildlife is effected by human development through research is the best way of learning how best to manage future development to reduce the detrimental effects it has on our native species.
Studying urban wildlife and managing urban habitat to encourage its spread are also important in getting the urban population interested and involved in nature and conservation. Of the 90% that now lead an urban lifestyle, only a small percentage have more than a passing interest in wildlife and natural history, and of those with an interest, most are likely to visit rural locations to enjoy their birding and wildlife-watching. Understandably, this is because rural locations often present much better opportunities to see wildlife in its natural habitat. This is also why scientific studies of British wildlife have traditionally been undertaken in rural habitats – with the conservation of rarer and more exotic species often high on the agenda. However, the majority of city dwellers are not particularly interested in nature and conservation, as it isn’t a big part of their everyday lives and it is not immediately obvious why it should concern them. Not surprising then that they are not likely to lend their support to an initiative to save wrynecks or nightjars for example, when they are unlikely to have ever heard of them. Organisations and societies whose raisons d’être are to conserve UK wildlife are now waking up to this and have realised that if they want to get the support of the masses, they must first get them interested and enthusiastic about local and accessible wildlife and conservation issues that are relevant to them.
Managing urban habitats to encourage wildlife back into cities, and dedicating time to the study of naturally occurring urban wildlife is the first step. Making the public aware of the richness of the urban nature that surrounds and is relevant to them is the next step. By making people aware of and excited about their local wildlife and encouraging them to share in the enjoyment of it has the positive effect of making them care more about it – and if people know what something is, a bit about it and most importantly where they can see it, then they are much more likely to want to protect it.
Increased engagement between people and wildlife in towns and cities, and increased understanding of the wider issues that effect the wildlife that is relevant to them, builds a respect and appreciation of the natural world, which in turn encourages increased support for other issues, including rural conservation.
The Tower 42 bird study group in central London is more than a testament to this. The group meet weekly during the spring and autumn migration periods atop the roof of one of London’s tallest skyscrapers – Tower 42 in the centre of the City of London. T42 is possibly the most urban location in the UK, and is in all likelihood the last location anyone interested in the study and spectacle of visible migration would choose to set up a watch. But this is precisely why it is important. Their findings (recently including sightings of little egrets, migrant meadow pipits, soaring buzzards, sparrowhawks, peregrine falcons and historical sightings of honey buzzard and red kite) are helping to build up a clearer picture of exactly how the spread of the urban environment is effecting the behaviour of our native species, whilst at the same time inspiring urbanites to expect the unexpected when it comes to urban wildlife, even in the most unlikely of places.
Bristol is the largest city in the south-west of England and like London, is not exactly considered a migration hot-spot. However, it does get its fair share of passage migrants and occasional rarities. It consists of a mixture of habitats, including mixed woodland, parkland, grassland, farmland, hedgerows, rivers, streams, canals, standing open waters and small ridges and valleys within its larger urban zone. Notable features are the River Avon, which runs through the heart of the city, down the Avon Gorge and into the Severn Estuary. Bristol is also surrounded by all kinds of zoogeographical regions, with large oak woods and moorland in nearby Devon and Wales to the west, the Severn Estuary, Wye Valley, Forest of Dean and Slimbridge WWT to the north, the extensive farmland of the Cotswolds to the east, Chew Valley and Blagdon Lakes and the Somerset Levels to the south, and further south, the Mendips and upland heaths of the Blackdown Hills and Quantocks. It is also far west enough to pick up the occasional migrant moving south-east into Britain from Canada or Greenland before making the journey south to the continent and Africa.
Cabot Tower has unimpeded 360º views across the city and is the best vantage point in Bristol to view urban visible migration.
Setting up the CTBSG has only been possible with the help of David Lindo and Ed Drewitt, and the support of the BOC and the Avon Wildlife Trust.
