East Budleigh Italian Sparrow

Since early November 2017 a male Sparrow showing characteristics of Italian Sparrow Passer italiae has been residing in East Budleigh with a House Sparrow flock. The bird was first found by local home owner and wildlife enthusiast Dave W and identified as a possible Italian Sparrow by local birder Chris Townend, who after careful liaison with locals, announced the news on Devon Birds on 11th Nov.

Possible Italian Sparrow in East Budleigh (c) Chris Townend - 16/12/17

Italian Sparrow is now treated as a full species, but relatively recent DNA research confirmed what many thought, that the species originated from hybridisation between House and Spanish Sparrows. They can be found throughout most of Italy, being one of the commonest birds in the country, with smaller numbers also breeding in France, Greece, Switzerland and Slovenia in regions neighbouring Italy. They're considered to be quite a sedentary species, although ringing studies have shown some sort of northward movement in the autumn. To cloudy matters though, House and Spanish Sparrows also hybridise in North Africa, but these aren't considered Italian Sparrows.

There have been several UK sightings of male Sparrows resembling Italian Sparrow over the years, some looking pretty convincing but others not so. The East Budleigh bird could well be described as being the most complete-looking candidate to date. Other recent records include single males in Cambridgeshire in November 2017, North Norfolk in August 2013, then again during the next two autumns, and  Hampshire in May 2014. There are many theories as to what these birds actually are and why they keep popping up. Are they simply odd House Sparrows? TreexHouse Sparrow hybrids? The results of a female Spanish Sparrow or two lurking in UK House Sparrow flocks? True Italian Sparrows? No one really knows.

Due to the complexity of this relatively new species and all the uncertainty around its identification, there have been no accepted British records of Italian Sparrow. In response to the submission of the above listed Norfolk bird, BBRC decided upon a 'Not Proven' verdict, although used the following wording in their published reply; 

"Ultimately, it was decided that while there was nothing wrong with the plumage of this individual, a 1^st record of this species would require DNA evidence and it was unfortunate that this eluded us on this occasion"

This gave Chris an idea. He contacted me around Christmas last year, and once I'd obtained all the necessary paperwork and permission from the Special Methods Technical Panel of the BTO's Ringing Committee, a couple of weeks ago the green light was given for me to trap, ring, and remove three flank feathers from the East Budleigh possible Italian Sparrow for the purpose of DNA analysis. Approved special method projects like this always come with strict guidelines and rules, all of which I ensured were adhered to throughout the whole process.

Thanks to the kindness of local home owner Dave W, and almost ideal mist netting weather conditions, the morning of Monday 9th April saw the first attempt take place in a private East Budleigh garden. Amazingly a mere 45 minutes and three House Sparrows into the session, the possible Italian Sparrow flew into the only mist net set. No tapes or sound lures were used.  The bird was quickly extracted, ringed, processed (with a multitude of biometrics taken), three feathers were then carefully removed and the bird was briefly photographed for research/identification purposes, before being released.

In short, the bird looked as good in the hand for Italian Sparrow as it does in the field. I'm not going to go into great detail here, but I do have a couple of comments to make regarding the above photos and following my in-hand observations.

1/ Although Sparrows do tend to have slightly longer upper mandibles, this bird clearly has a slight deformity with an even longer and more hook-tipped upper mandible than expected. It hurt more than any Sparrow I've ever handled before that's for sure!

2/ The chestnut crown, as can be seen in the middle photo above, showed lots of buff flecking throughout. It wasn't grey and was only present at the very tips of the feathers. Sparrows often show pale fringing to crown feathers, particularly early in the season, so the presence of this is not at all surprising.

For anyone interested, the possible Italian Sparrow is still present today in the same general area. For viewing directions see Chris's original Devon Birds post here;

I just want to again thank Chris Townend for being the catalyst of this project, the home owner Dave for his hospitality, bird ringers Mike (my trainer) and Peter (a local A ringer) for accompanying me during this ringing session, and all the other individuals and organisations who offered their support and/or advice during the build up. Of course special thanks and recognition must go to the BTO for allowing this exciting and potentially highly educational development to take place, for which I've been humbled to be a part of.

So it's now over to Prof Martin Collinson of Aberdeen University to do what he does best...

BTO NEWS Count

Looking at the weather forecast for the week, and the tides, this afternoon looked like my best shot at completing my BTO Non-Estuarine Waterbird Surveys (NEWS), I signed up for all the sections between Weston and Branscombe - a three mile stretch of beach!  I parked up at Weston, walked down to the beach and then along the rocky shoreline to Branscombe where Dad kindly met me.

Weston Beach - with the first interesting looking rocks in the distance

First time I've been down here for umpteen years, and I'd forgotten about this rare looking scrubby valley that leads right down to the beach - bet there's been a few Sibes in here over the years!

This is what most of the shoreline looks like at low tide between Weston and Branscombe

Another pic of the rocks - I love the dramatic light in this pic though

I can't tell you how pleased I was to get to here! Branscombe and Dad

This stretch of coast isn't known for it's wading birds, so three Oystercatchers and a Curlew exceeded my dismally low expectations. A Grey Heron fishing in the rock pools was also a bit of a surprise.  On the sea the waves made viewing difficult with just singles of Great Crested Grebe and Red-throated Diver, three Razorbill and a Guillemot noted. Over the sea three Common Scoter west were the highlight, along with a dozen or so Gannets and a reasonably steady passage of large, Common and Black-headed Gulls.

Looks like we've got a few rough days ahead, and there seemed to be good numbers of large Gulls around the patch today.  I will be disappointed if by the end of the week I've not seen a white-winged or Caspian Gull. Watch this space...

Donkey Ringing

....well maybe not quite, bird ringing at the Donkey Sanctuary yes.

I'm really privileged to be able to ring here as this charity owns and manages acres and acres of superb wildlife-friendly habitat, containing a surprising variety of different habitats too.

Friday morning I spent three and half hours with two nets up, which resulted in 34 birds ringed.  One of the first birds in the net was a Nuthatch, but not any old Nuthatch. The only other time I've ringed at this location was back in May 2012, and during that session I caught one Nuthatch - the same Nuthatch! 

Love the powerful dagger-like bill

She was a breeding adult when I caught her back in 2012, thankfully she's still a she!

In keeping with the trunk climbing nature of this species, the real highlights from the session were two absolutely beautiful Treecreepers.  Not an easy species to age, in fact it's only recently that a few features have been noticed. Even so, I was confident ageing one as an adult, but the other I've had to put down as a '4' (ringers age code for not a clue!).

This bird was considerably longer billed than the first,  so maybe a male?

The same bird. Incredibly it was two grams lighter than the Wren we caught an hour earlier!

I really look forward to doing more ringing here. It will be interesting to learn how many birds are making use of this well preserved part of East Devon.
