How to get an awesome nest record of a Peregrine!

"Since the first web camera was used on a Peregrine nest in Brighton back in the late 1990s, our knowledge of what goes on in the lives of Peregrines has come on leaps and bounds. Even back then the grainy, low resolution pictures that updated every minute (if you were lucky) gave us insights in to the lives of these then rare birds. Over time improved technology, infrared light, high definition imaging and faster broadband connections now means we can watch peregrines 24-hours and all year round. As a result we can gather information about what makes peregrines tick that even committed Peregrines researchers fifty years ago could never have achieved by watching nesting rural peregrines (under a licence) from afar."

"Web cameras allow us to hear baby peregrines cheeping to their parents days before they hatch and discover what prey is being brought directly to the nest. We can record accurate dates of when eggs are laid and when they hatch. And usefully, from a ringing perspective, it allows us to observe who is who at the nest site. Cameras help us read ring numbers of Peregrines and follow individuals. More recently interlopers have been observed visiting urban Peregrine nests, identified by their plumage, gender or colour rings."

Peregrine - Fellowes

"At some nests, young birds from the previous breeding season have been observed visiting their parents and nesting site, some staying throughout the nesting season helping to incubate eggs and feed chicks; a form of cooperative breeding. This behaviour is likely to increase as the urban peregrine population increases further - it pays for the younger birds, often males, to stay with their parents for an extra year to develop their life skills and avoid getting beaten up by other Peregrines if they wander further afield. Web cameras are also useful for: detecting new breeding birds that have appeared within a pair; extra-pair copulations whereby a male or female Peregrine sneaks off to mate with a different bird elsewhere and increase their gene pool; detecting inbreeding and much more."

Ed - There are several nests that can be viewed online and some have just started laying over the last couple of days. A selection of some active ones are below:

Norwich Cathedral Peregrine
Sheffield Peregrine
Brighton Peregrine
Nottingham Trent University Peregrine
Bath Peregrine

An interesting behaviour that David Morrison reported to us recently regarded a brood from last year that fledged and one of the chicks joined another nearby Peregrine nest and was accepted by the parents. This chick fledged with it's new siblings several months later.

Ringing Course at Chew

I have just been on the Chew Valley Ringing Course in Somerset. This long standing course offered training in mist netting of various species covering Reed habitat, garden birds and also hirundines. Together with this information on moult stratagies and other catching methods were also given.

This year there were mainly trainee ringers attending the course and we had a good mix of birds caught and we were able to look at their plumage in great detail. This is a regular ringing site so there were plenty of known age birds. About 300 birds were caught during the 3 days including a bird that was ringed further north by West Wiltshire Ringing Group and also an adult Sedge Warbler that was already ringed by the French Ringing Scheme (Paris)! Ringing details are on there way.

Ringing Courses are an excellent way for ringers to get extra experience in various aspects of ringing and also be assessed for permit upgrades. These are particularly useful for ringers applying for training endorsements. Courses are currently full for this year and usually run from June to October but future courses will be on the BTO website next year. It is advisable to book early!

Thanks to all that participated on the course and to Ed Drewitt for the photos and Mike Bailey for the image of the Paris ring.

Urban Peregrine shenanigans

Ringer Ed Drewitt writes:

In 2007 we ringed our first two peregrines chicks on Bath Cathedral, Avon and added unique colour rings, so that they could be identified in the field and their relationships and behaviour studied. One of these Peregrines, AA (left chick) was allowed to stay by his parents at the site.


A year on and just as the 2008 chicks were about to hatch, the breeding male disappeared for unknown reasons. For that season, the young male that hatched the previous year helped his mum rear the chicks.

In 2009 he was still in residence with his presumed mum, being unringed we will not know for sure. To prove her identity I collected the moulted feathers of both the parent and AA. I've just received the DNA results back which reveal the two are related - ie he has paired up with his mum!


With the female (mum) being unringed we didn't know for sure if this bird was the same female in 2010 or this year (unless I did DNA tests again) but a remarkable story never the less. This year the well watched pair have 4 eggs (laid 1 week earlier than last year) and are doing well. As far as I can tell this is the earliest in the UK this year! Perhaps a reflection of an experienced pair (and therefore the same female too) and settled weather.

Thanks to Ed Drewitt for letting us know and Ian Sparrowhawk (chicks photo) and Mike Fisher (Peregrine AA) for the photos.
