London House Sparrow Project ends

I received the final newsletter of the London House Sparrow Project this weekend. Here are a few extracts from the text:

“After 5 years of counting your local sparrows, the project is now coming to an end. We are very grateful to all of you for your kind help over the years, whether you helped feed the sparrows, allowed us access to your gardens, or plied us with welcome cups of tea.

“So what have we found after five years of feeding sparrows? Feeding mealworms during the summer increased nesting success of sparrows in every year. However, we only saw an impact of feeding on adult numbers when we fed year-round seed as well as mealworms. [A graph then shows that] adult numbers increased on fed sites, only after seed feeding was introduced in 2007. This suggests sparrows lack sufficient insects to feed their young, and also seed to get them through the autumn and winter.

“With a focus on a few sites over the winter we've been able to work out the “survival rates” (percentage surviving from one year to the next) of our sparrows at the fed and "unfed" sites. Analysis suggests that about 51% of our colour-ringed birds are getting through the winter months, which is pretty much the figure that is cited in other studies as the percentage annual survival for house sparrows. So it doesn't appear that our sparrows are unduly suffering over the winter. It does sound like a lot of birds perishing each year - we have to remember that such small creatures are often rather short-lived, and that maintaining the population depends on a lot of young being produced to counter this.

“For our last fieldwork we looked at a few sites this summer to check on our survey methods for fledglings” [this included the Cliffview Road site; Bird Champ].

“Meanwhile, our exciting new project has begun. The RSPB House Sparrow Parks Project. Officer, Jacqui Weir, with the help of the Royals Parks, the London boroughs and SITA Trust, is trying out large scale experiments on London's green spaces, to find out what sort of park management is best for bugs and seeds, and therefore sparrows and other birds. This is an amazing project which will hopefully produce improvements to London's grassland biodiversity! Jacqui [jacqueline.weir@rspb.org.uk] is the primary contact for your enquiries about this work

“Once again thank you to everyone for your amazing support, we could not have done it without you. And please do visit http://www.rspb.org.uk/ for more details of how you can continue to support our work. In the meantime, please keep looking after your local sparrows!”

So that’s it. The end of the London House Sparrow Project. We’ll miss Chris Orsman’s regular visits here and thank him again for the generous donation of seed, feeder and nest boxes for Hilly Fields Park.

Four Mistle Thrush, no less!

Despite best efforts I haven't managed to get into the park for a long time. I used to think that being retired would give me lots of time to myself, but reality is the reverse: I had more free time when I was fully employed!

In recent weeks it seemed that every time I had the opportunity to get into Hilly Fields it was either very windy or raining or Prendergast School was just out. The three worst time to see the birds.

This morning was delightfully different. First I filled the birdfeeder in the Quiet Garden then took a walk across the park. That's when I spotted the first Mistle Thrush in the West field just north of the meadow; a few moments later it was joined by another and a couple of minutes later another pair showed up. They were seeking food in the grass and gradually making their way south to the meadow.

I didn't have my camera with me, which is rare, so took a few photos with the mobile phone. In my excitement I forgot that its zoom facility is purely electronic so, since I took most photos at full zoom, the resulting jpegs are only 15KB instead of the normal 3MB and appallingly bad resolution. The best of them has been put through Photoshop to enhance the three birds but you still need the arrows to see exactly where they are.

Kestrel unperturbed

Cllr Mike Keogh emailed me some photos he took a couple of days ago of the Kestrel in the meadow. Mike wrote:

"Have you seen the kestrel at the bottom of the school to bottom Montague Ave path, on lamppost just before trees. It is in and out of the meadow ... and hangs out on top of lighting column looking quite scruffy and unperturbed by passers-by."

This photo shows the Kestrel on a lamppost on the path near Prendergast School, which is in the background.

Thanks Mike.

The Kestrel's back (& me too!)

After a few weeks absence on holiday in the Scottish Highlands and then essential maintenence around the house and garden I am, at last, back to the normal routine.

I must mention (because this is very rare) that the Highlands were dry and very hot: up to 30 degC. and only one rainy day. There were plenty of Osprey nearby, one even took a fish just 100m from our apartment, and no shortage of House Sparrows.

For the past few weeks Chris, from the RSPB, has been surveying Cliffview Road and this side of Hilly Fields weekly instead of monthly. When he was here on Thursday, Chris told me the weekly visits have been very successful, from the point of view of the London House Sparrow Project, but next week could be the last of the more frequent visits as breeding is almost over for this season.

I was in Hilly Fields this afternoon and met Keeper Justine who has quite an interest in the birdlife and brought me up-to-date on what was around. I filled the feeder in the Garden and then wandered over past the Playground when suddenly a Kestrel swooped down on something. Whatever it was must've got away because the two photos I managed show the Kestrel without a catch.

RSPB weekly survey

If you see this man with binoculars looking towards the roof of your house, all is well, he's not casing the joint!

This is Chris Orsman from the RSPB on his now weekly survey of House Sparrows in the Cliffview Road area. Chris is a key member of the London House Sparrow Project team which, until recently, surveyed 66 sites across London on a roughly monthly basis. The number of sites has now been reduced to permit weekly visits to the more active sites - including ours.

Chris will be in Hilly Fields park peering into our gardens and also in one or two gardens in Cliffview Road.

Some of his visits may be quite early in the morning but most surveys in our area will be on Wednesdays.

Nests galore

I haven't found the time to get into the park for two or three weeks, so today's findings quite made up for that.

First I found, in the quiet garden, a pair of Robins feeding a young one on the ground. All three had flown before I could get my camera out.

Next, near the school, I spotted a Mistle Thrush. It flew into a tree, straight to its nest and proceeded to feed its young. There were at least two of them. While watching that, Blue Tits were frequently flying into and out of the same tree. Just the other side to the Mistle Thrush nest was a natural hole in the tree with an occupied nest.

Around the other side of the play area I found one of the nestboxes made by pupils of Prendergast School was occupied by another family of Blue Tits.

Finally I returned to the Mistle thrush nest and managed to get a quick photo there too.

Quite a successful hour.

London House Sparrow Project

I’ve just received a call from Chris Orsman from the RSPB London House Sparrow Project.

Until now, they've been monitoring 66 sites around London on a roughly monthly basis, half of them fed with live food and the other half (including ours) are control sites. They are now dropping sites with fewest House Sparrows and intend to monitor the remainder (including ours) on a weekly basis.

To this end Chris, armed with clipboard and binoculars, will be peering over garden hedges around Hilly Fields Park surveying the nesting sites, many of which are in our roofs. Before he begins this new phase next week, Chris intends to visit those houses to introduce himself and assure you he’s not up to no good!
