Knowing that not everyone is on Facebook, here is the latest naturestimeline imagery in all its glory or not, as the case may be.
A naturestimeline Facebook page production – some further randomness
Wow, having looked back through some recent photographs, I can’t believe I’ve managed to capture this. After all, I am a truly amateur photographer unlike some.
Look towards the middle left portion of the first image and just above the telegraph wires, a lightning bolt is revealed. More usually my captures end up like the following image (click on link for full-sized image).
And when it wasn’t raining over recent weeks, a walk in a local private woodland managed for pheasant shooting revealed this beautiful creature, a Silver-washed Fritillary butterfly. Again, click on link for full-sized image.
Before I venture into the mayhem of March 2013, I must apologise for missing out the first Butterfly emergence of the year. This appeared in the form of a Red Admiral (Vanessa atalanta). Find a splendid example of this beauty below, from Finn Holding’s The Naturephile Flickr account. *Finn Holding’s website is one of several, my readers might find of interest under My Favourite Blogs link on the main page.
My 19th February sighting came about whilst undertaking a Willow Tit (Poecile montanus) survey at a local woodland. Indicated below, you can see the trend of first emergence dates of Red Admiral over time.
The United Kingdom’s mad March weather was well documented by the media and the official climate statistics are below.
I won’t bore you with my personal weather station’s data, other than reproduce the following chart.
I have highlighted in red and blue, the figures that stand out the most and these were the Mean Temperatures of 2.8c, the precipitation amount of 108.6mm (largely from two heavier interludes, some of which fell as snow). Finally, the dominant wind flow from the Northeast with very little coming from the West. In spite of this, I documented 11 phenology events throughout March and I will now refer to these below.
March 5th brought about both the first Brimstone butterfly (Gonepteryx rhamni) and the first Queen Wasp from the genus (Hymenoptera).
March 7th saw the first attempts at nest-building by Blackbirds (Turdus merula).
The 9th of March saw us venture out into the local countryside for the first time in weeks, having endured another bout of illness. It was to prove a good decision with 4 events being logged that day, which were as follows. A first heard singing Yellowhammer (Emberiza citrinella) sadly lacking the usual close correlation with their return to territory dates, as emphasised in previous posts. The same day also produced further yellow natural indicators with first Wild Daffodils (Narcissus pseudonarcissus) in flower and Flowering Coltsfoot (Tussilago farfara) only one day behind their 2012 emergence dates. Lastly, it was wonderful to hear the first song of Woodlark (Lullula arborea), a sound clip of which is available here. *It is just possible that I could have included a probable singing individual from the 19th February.
The 13th March provided a rather late Lesser Celandine (Ranuncula ficaria) in flower, which made sure we continue the yellow theme of spring.
Two Thunder days were to follow with the first of the season on the 16th March and the 2nd Thunder day, coming courtesy of the 19th March.
A final March phenological indicator arrived courtesy of a Northern Wheatear (Oenanthe oenanthe). This witnessed on another local trip to our hillsides on the 29th March. This species, at least according to my records is seemingly bucking the trend of earlier arriving migrants, as illustrated by comparison of actual dates against rolling averages, see below. Furthermore, based on evidence from elsewhere, I am fortunate to have witnessed at least one migrant bird species as they appear to have been held up on the nearby continent, no doubt partly due to the persistency of the wind direction aforementioned.**
Let’s get graphical and photographical, firstly a few images (not the best quality, as I’m no photographer).
And now onto the charts, please refer to past calendars in order to understand the individual actual day numbers, against which you may recognise a developing trend over time, when making comparison against rolling averages. In order of appearance, I give you the following.
Some events are starting to show remarkable consistency, with rolling averages either slowing down their descent to earlier dates (recent cold winter impacts) or remaining similar over recent years.
** Yes, I haven’t even achieved a singing Chiffchaff (usual date, 11th March) yet alone an early hirundine or something along similar lines. Perhaps, not so amazing, considering the bizarre weather and the fact, 10 days were witnessed as snow falling days, alongside 19 Air Frosts.
