Tree Following ~ Silver Birch in June



This post is the fourth in my Tree Following series, part of a wider project run by Lucy Corrander from the Loose and Leafy blog. I am following a Silver Birch in Suffolk, UK. You will find the other Tree Follower links for June 2014 here ... so do take the chance to go on a virtual exploration of the arboreal world!



WELCOME, Tree Followers et al, to my June update.

My Silver Birch (B. Pendula) has been looking green and leafy since my last update. The photo above was taken on 10 May, shortly after I posted my May bulletin on Mr Linky.

The weather has been mixed so far, with grey cloud being a dominant feature. The temperatures have been mild but it has been cool at dawn. The Blue tits are probably the most frequent visitors to the coconut feeder on the Silver Birch - and as predicted, the roses are in bloom.



DETECTIVE WORK

The month (by which I mean the weeks between posting my May and June TF reports) began with a slight concern. I noticed another birch nearby, and began to wonder whether I was right in identifying this one as a Silver Birch after all!

The two trees seemed similar at first, and in fact, I had not noticed that there were differences. Something twigged (sorry), and I began to realise that the two were by no means identical. I erroneously assumed at this point that the other must be a Downy Birch - purely on the grounds that it differed from my tree.

However, I looked a bit more closely, and noticed that the leaves on 'the other tree' were more forked and less saw-edged than my tree. The other tree's leaves had deeper indentations than the leaves you see above. They also appeared a bit more like a squashed maple leaf and less like the shape of a kite.

Thanks to Dr D.G. Hessayon's book on trees and shrubs, I have come to the conclusion (and I hope I am right) that my birch is indeed a Silver Birch (B. Pendula). I believe that the other tree is probably the Swedish Birch, B. pendula 'Darlecarlica'. It is not in my gift to photograph this one, but you will find a good picture here.

Mystery solved! I feel somewhat chastened to think that it has taken me this long to make this discovery, but there you go.

BIRD LIFE

I decided to tighten up a bit on my bird observations, so I began to chart the birds I saw on my (B. Pendula) tree or on the feeders hanging from its branches to see if any daily patterns or surprises emerged.

Sightings include (roughly in order of frequency) ...
  • TFb7  Robin (frequently below feeder)
  • TFb2  Great tit (frequently on feeder)
  • TFb6  Blue tit (frequently on feeder)
  • TFb10 Dunnock (frequently below feeder)
  • TFb4  Blackbird (frequently below feeder)
  • TFb8  Magpie (frequently dive-bombing feeder)
  • TFb11 Starling (on or under feeder, frequently three birds at a time)
  • TFb9  Wood Pigeon (perching around the feeder area)
  • TFb12 Carrion Crow (on fence at back of Silver Birch) - first seen on 14 May 2014

I also have a new bird species on the block, the beautiful Goldfinch (TFb13). I had planted up some bedding plants in a pedestal planter on the patio, when minutes later I looked out to see two Goldfinches perching on the metal rim. One flew up into the Silver Birch while the other plucked some strips of fibrous hanging basket liner, presumably for a nest. The Goldfinches returned today, and I am really hoping that they will stay around as they are such colourful and delightful birds. You will notice that the one below is not on my Silver Birch! Sadly I didn't have my camera to hand when the Goldfinches landed, but these are such fine birds (despite their messy nests) that I wanted to re-post an earlier picture.


Goldfinch

The only other new bird to settle in the vicinity of the Silver Birch was a sleek brown one with a slightly speckled chest, slightly larger than a Satrling. I didn't think it was a Mistle Thrush as its speckles were not very pronounced. I wondered if it was a female Blackbird like this, although its eye markings were more prominent. Today I saw the bird again in the company of three other juvenile Starlings - mystery solved, I think!We also think we had a fleeting glimpse of a Coalt-tit, but are not entirely sure. This would be another new species for my Silver Birch birdlist, but I won't add it until it re-visits and I can be sure.
There have been no further sightings of ...
  • TFb3 Long-tailed Tits
  • TFb1 Great Spotted Woodpecker
  • TFb5 Song Thrush

However, the members of the Blue tit brood have delighted us with their antics on and around the coconuts that hang from the Silver Birch.




INSECT LIFE

The main insect immediately below the Silver Birch was a large Garden Chafer (Phyllopertha horticola). It was busy devouring a leaf when I looked down and saw it. According to the RHS, this species can cause a lot of damage to lawns.



We have been very excited this month as BBC Springwatch has come to our (relatively) local nature reserve, RSPB MInsmere. I first spotted the colourful Ruby-tail Wasp on the Minsmere site back in August 2012. It was scuttling over the surface of a wartime tank-trap. I am delighted to report that I have had several more sightings of this unusual insect on sunny days on the wooden posts around my patio, metres from the Silver Birch. Of course, the juxtaposition between the birch and the wasp may be of little significance: who knows ...

I am sitting at my window as I type, peering out into the semi-darkness. We have had bursts of warm sun today. We have numerous moths flying around the kitchen and a pair of skittish bats in the garden, flitting alongside the feathery forms of the Silver Birch branches. It will soon be the longest day.

Hi Caroline, what a good job you've done following the silver birch by observing it and its visitors so closely. I am so impressed by the large variety of bird visitors. And that ruby wasp is very colourful - definitely no camouflage there. We're nearly having our shortest day - I always look forward to post June 21 so I can have longer in the garden before it gets dark.

Lovely post. The young blue tits are adorable and the ruby tailed wasp is amazing, I've never seen one of those. Lovely that you've got goldfinches in your tree too, lots of them now around where we live

Hello Caroline. Fascinating about the leaves - and lovely clear photos. Haven't heard of a ruby tailed wasp before. Looks special.

Incidentally, your link from the link box works fine. Don't know why it didn't work when you tried it. Just one of those internetty things.

Clever leaf detective work! And what a wonderful selection of bird and insect life - a veritable zoo!

Checking on your tree today. Humm different than what we first thought. Enjoyed my time here today. JC

Goodness - how did I live all these years without coming across a ruby tailed wasp before? Along with the goldfinch, you are certainly getting a lot of colourful visitors. Your close observations put me to shame - I missed updating altogether on my silver birch last month but I am determined to do so in the next couple of days. It won't be as well-observed as yours, though.

What a lot of beautiful birds you have. I love the gold finch. I have never seen the ruby tailed wasp before, he is lovely. I think a birch was a good choice of tree to follow, I have noticed mine is teeming with life and birds love it, specially long tailed tits.

Lovely photos and great detective work!

Great post, first time visiting ..will be back.
Came to look at your tree, great job working it out. Just started looking at trees this year, hoping to name them all at my local park. In the next few weeks I'm going to take a sample of leaves and press them in a book, I bet there will be a few surprises along the way.

Thank you to everyone for their lovely comments - and thank you to those of you who are also Tree Followers. What a lot we are learning from the variety of trees covered in Lucy's project.

Great shot of leaves & catkin - my favorite of the bunch.

Great research, isn’t it lovely what we can discover when looking into things? Your bird photos are great, I love having birds around in the garden but I rarely get good photos of the smaller ones.
