Post 465 - Magical Mesmerising May Lillies

Hey everyone, post 465 and something a bit special today. Last month I went out for a walk looking for something special, something completely different to what I found but something I've been wanting to see again for a long time. Adders! I saw one quite close up when I was very little, almost too close up, as it was reared up on a path in front of me when I was walking in our local forest. I saw another in Scotland but that was a few years ago too. So our family went looking for them at a Yorkshire Wildlife Trust reserve that's meant to be very good for them but we must have been too late in the day as we didn't see any.

Still we saw some Common Lizards, the first this year, and had a nice walk around the reserve. As I passed a bit of it I noticed a tiny fenced enclosure and wondered why it was like that. There was a plant inside that I didn't recognise so I took a photo and thought I'll look it up when I get home.

I happened to be tweeting for #wildflowerhour a few photos of things I'd found. I'm not much of a botanist so it's just plants I find that look beautiful or unusual. I'm starting to learn a bit more by doing this so then I tweeted about my mystery plant to see if people could help me out.
So I had some botanists on the case (thanks @botanicalmartin, @RubusCaesius3 , @dave_renwick, @BSBIbotany ) and after a while people decided what I had found was in fact a May Lily!

The patch of May Lillies I found
Well, thanks to these botanical friends I knew what it was and I also knew it was very rare. Most of these people haven't seen this plant as it's so rare here in the UK!

Well as this photo was of the plant in bud they hoped I'd get back to take a few photos of it in flower. It's a bit far from me but knowing it was a bit special, well I had too really. So last weekend we managed to get back and thankfully the lily was flowering! I managed a few shots but with the flower being in an enclosure and it being a bit windy they aren't the best shots I've ever got but I hope you like them.

I had to do a bit of research so here's a bit of info on them too:
A shot at flower level

  • The May Lily is also known as False Lily of the Valley. I think that's a bit unfair as I have Lily of the Valley in the garden and I think I prefer the May Lily.
  • I prefer it as it's a small delicate plant. In the patch I found it is quite small but it can be between 2-8" tall
  • It's only found in four locations here in the UK but is more common in mainland Europe.
I love the unusual way they grow.
  • The May Lily is an indicator of ancient woodland and it likes shady places with acidic soils.
  • A big threat to it is the loss of these habitats. it was a lot more common in the 17th Century.
  • Its latin name is Maianthemum bifolum and generally only has two leaves (bifolum), but might have four sometimes.

  • The first bit of its latin name, Maianthemum, refers to its flowering period but it does flower into June as well.
    A flower close up.

    • It is a perennial herb that spreads through its roots.
    • It has lovely white flowers that are mainly pollinated by flies.
    • Once pollinated it can produce sweet red berries which are poisonous in large quantities to us but not to birds, though they don't seem to be too keen on them.
    Well, what a nice find! It more than made up for not finding the Adders I had been looking for but I guess I'll have to keep trying for them, and maybe get up a bit earlier too :-p

    Hope you enjoyed,

    Post 464 - Brilliant beginnings of baby birds

    A Starling fledgling on our bird table
    Spring is a fantastic time of year – full of new life! Something that I've been watching closely this year are the fledglings – we get literally dozens of baby Starlings and Sparrows all fighting for attention and some space on our bird table waiting for Mum or Dad to feed them. We have so many because they have taken up residence in the eves and roof of our house! They have a steady supply of treats on the nearby bird table. Quite often when they are being fed we can hear the nestlings chirping away. Dad built a colony box at the side of the house to see if they'd rather live in there or to provide extra room, but no, they're quite happy where they are! It's lovely to watch them flitting about but we do have a bit of a problem with droppings…. hmm, a small price to pay for being so close to nature I guess! 

    We also have Blue Tits nesting in a box on our Apple tree, and some Dunnocks nearby too. But the inspiration for today`s post is thanks to a nest of Blackbird eggs that my Dad came across. He was tying back some clematis on an arch when he flushed a Blackbird which was sat on a nest. There are four beautiful blue eggs in it, and Dad very carefully took this photo of them. He then left it well alone and the parents came straight back to it to keep the eggs warm. The clematis will have to grow a bit wilder this year as we don't want to disturb the birds.
    The Blackbird nest that inspired this blog!

    Dad showed the picture to Mum, who then started raising some very interesting questions, many people may already know the answer to these questions but it made me think if Mum wasn't sure about all the details, maybe other people wouldn't be so sure either, therefore the focus for this post is… “What goes on inside the female bird during the egg making process!?”

    Well with the help of the internet I discovered the following:
    • For birds, their courting process and behaviour takes quite a while and includes many stages.  From claiming territory there follows an elaborate courtship including dancing, calls, spectacular flights (love watching Lapwings do this) and plumage, it is all so that the male can demonstrate to the female how healthy and strong he is, which means that his chicks will be healthy and have the best chance of survival.
    • Some birds mate for life like the Gannet, often travelling unbelievably long journeys to meet up again, while others find a new mate each year, like the Blackbird
    • Birds don't have the usual type of reproduction organs that we are most familiar with.  Instead they both have Cloaca which are little openings.  Through this they do everything, including urination, defecation and mating.
    • During the breeding season, the Cloaca of both male and female birds swells and protrudes slightly, and the male`s Cloaca holds their sperm until such a time as they are able to mate, when it is then deposited into the female and travels to meet the female's egg which is stored in her ovaries.

    - this one is feeding itself now
    • If you see a pair of birds mating, keep your distance because if you distract them and interrupt proceedings, it can harm their bond with each other.  It is a very brief interaction where the male balances on the female, and then it is over.
    • Out of all the 9000 species of birds, all of them lay eggs rather than producing a live off-spring.  This is believed to be due to the fact that as birds have such fantastic mobility and agility, they need to maintain their ultra-light anatomy so carrying around a clutch of chicks inside them in the same way a dog carries a litter of puppies inside her, just wouldn't be possible.
    • Female birds carry one single egg at a time and due to its weight impacting on her ability to fly, as soon as it is viable (ready to be laid) it is. A Blackbird for example generally lays 3 or 4 eggs per clutch, laying one egg per day. Each egg has a protective shell around it which has already hardened to keep the precious chick safe.  While we think that eggs are extremely fragile they are actually designed to withstand a huge amount of force, to be able to withstand the parent sitting on it whilst incubating it for example. Eggs are oval and so the same engineering principals of an arched-bridge apply, the convex surface can withstand much more pressure than other shapes.  The shells need to be robust because many, many predators would just love to get their beaks, paws or claws onto the protein-rich contents of the egg.

    • One of the vital components of raising healthy chicks to fledgling status is the location and stability of the nest.  This is the task of the male bird and again is to demonstrate to the female his suitability.  A European House Wren is said to build up to 12 nests in varying locations until a female grants her approval and chooses him as her mate. The nest must be well constructed and inconspicuous. Birds have varying techniques for building the perfect nest and some will line them with moss, lichen, leaves and feathers for warmth and comfort, others will produce a sticky substance to help the eggs to stay in place. Some breeds of bird will stay with the eggs throughout the entire incubation period, a Hornbill for example will seal herself into the nest with only a small hole enabling her mate to feed her through.
    • Incubation can take between 13-14 days and then comes a frantic period of feeding the brood, often an ordeal in itself with much success depending on the weather, accessibility to the right insects, etc. If enough food is brought to the chicks, fledging then takes place, usually  about a fortnight later, though this can vary with species, for example the longest incubation period for any bird is 64-67 days with the Emperor Penguin!
    Well we'll be keeping a quiet eye on the nest to see how things go for our new Blackbird pair, and also look forward to seeing more fledglings. One of the things that makes us smile most on the bird table is watching the little Sparrow and Blue Tit chicks sat fluffed up shaking their wings begging for food. They can be sat right next to the food that their parents pick up and feed them but it seems to take a good while for them to realise and to start helping themselves!

    Hope you enjoyed,
