A Tit Without A Tail

I had seen it twice in the third week of May. Up in the hawthorns on Eastern Road - a very small bird looking from below like a ball of pale fluff, always in the company of a Long-tailed Tit and moving rapidly between branches and trees. It kept making a high "tseeping" sound and I had thought: Goldcrest? Very recent fledgling of some sort? At times, it hovered between branches fluttering its wings as if to keep airborne, but usually it had no problem flying fast or in a reasonably straight line.Then, on 22 May while doing the monthly bird survey with Sue, we both saw it and  reached the conclusion that what we were looking at - from the visible head markings and general behaviour - could only be a Long-tailed Tit without a tail.

Back home, a quick surf through Google proved that tail-less tits, though not common, are seen from time to time. The lack of a tail is usually the result of an accident or a predator attack. It doesn't seem to affect their ability to forage and frolic (like a "manic pom-pom" is how one tail-less tit is described) and the tail normally grows back after about four weeks. I haven't been able to photograph the Eastern Rd pom-pom, but here's a pic from the web::

From Asigaru's Nature Diary
Long-tailed Tits are nesting in the densest bramble scrub you could find on Eastern Rd where their chicks should be safe until fledged. This is good news as they are one of five key species among Hilly Fields regulars which re-assure me that the park is still providing a good diverse habitat. The other four are: Blackcap, Great Spotted Woodpecker, Jay and Mistle Thrush. Yes, I know you could add the "at risk" House Sparrow, the Dunnock, the Greenfinch (not seen often and in decline nationally), but I'll stick with my "big five" for now.

Sue and I saw four of those five key species during our May survey, the only absentee being the Mistle Thrush. There were plenty of birds singing, but the foliage is back on the trees and seeing the smaller birds is getting harder again. Our list for that day (of birds seen or heard) is as follows: Blackbird (6), Blackcap (1), Blue Tit (4), Crow (3), Chaffinch (1), Chiffchaff (1), Collared Dove (2 - an unusual sighting on Hilly Fields), Dunnock (1 - singing in the Vicars Hill border), Feral Pigeon, Goldfinch (3+), Great Spotted Woodpecker (1), Great Tit (4), House Sparrow (2), Jay (1), Long-tailed Tit (3), Magpie (2), Ring-necked Parakeet (1), Robin (5), Starling (6), Swift (2 - soaring overhead), Woodpigeon (3) and Wren (5+).  22 species - one of our best results. The Chiffchaff is only the second we've heard on Hilly Fields since their arrival in the UK in late March/April.  And it occurred to me that the Jay would be able to hide itself better in thick woodland or scrub without that bright blue wing patch which gave it away this time. Here's a photo of one I took a few days earlier on the open edge of Hilly Fields wood:


Around the park in general, spring has sprung with a vengeance after the extended midwinter cold. All of the trees are in leaf, the horse chestnuts have their creamy-white flowers, the May blossom has appeared on the hawthorns, there are daisies and bulbous buttercups and even the occasional bee or butterfly. And one particular plant - as you can't fail to have noticed if you've been there recently - is romping away:


Yes, you can hardly see the trees for the cow parsley.

  1. I've never seen a tail-less tit; I would've thought they'd be problems with balance, particularly when flying but this one seems to have adjusted very well.

    Greenfinches are in the neighbourhood, a pair visit our feeder fairly frequently.

  2. It did flutter its wings very fast once or twice which might indicate some problem with balance, but otherwise it hopped between branches in the usual acrobatic manner & seemed to have no problem flying. Yes, Greenfinches are still around but we've seen or heard only 7 in the last year. I believe their population has fallen by about a third in the last decade due to a disease called trichonomosis.
