Spring peak has arrived and Summer is just around the corner too, as the birds are singing, the bees are buzzing, the trees are leafing and this blog is…… well desperate for content if truth be told.
Fear not, anybody who knows me will realise that I am still active over on Facebook and I haven’t disappeared into the oblivion, take today’s Facebook Naturestimeline cover update below, for instance.
And then there is the original, unedited, uncropped version (beware, large upload) for all my fellow nature lovers to admire.
Isn’t he or she a beauty eh! My advice to you is, should one need a boost for their wellbeing, just listen intently to birds such as the one shown above, singing lustily away at dawn or dusk amongst a cacophony of other birdsound. Of course, there are times when they’re not over vocal as when raising their own family, it is best to be quieter then as noisy adults make for noisy children, you know. As for my own voice, it can often be heard over on LinkedIn. I like to participate in various LinkedIn Group discussions over there or simply make worthwhile connections with fellow naturalists and conservation professionals as the more the merrier, the bigger the conservation movement. I am an occasional Google+ community user as is evidenced by the badges on this page as well, of course.
So finally, it is time for a request. Wherever you find yourself loitering about online, do please let us know. As you are my audience, therefore we should get connected and continue to fight our fight together, for the good of the Natural World.
Looking back at January 2013, were my local climatic conditions much different to that of 2012?
Firstly, in the United Kingdom, 2012 began as “the year of the drought” * with recorded precipitation totalling 32.8mm in my neck of the woods. By comparison, January this time around looked like this.
In total, we received 61.6mm, which is still below the revised 1981 to 2010 mean by approximately 25% or so. What about the Air Temperatures?
January 2012 was mild in comparison with some 11 double-digit Fahrenheit Maximums being achieved back then and unsurprisingly a mean of 0.8cabove the long-term average, mentioned previously. This time around, January2013 saw the following daily Air temperature trend.
Due to almost two-thirds of January 2013 being in the cold to very cold category, it is unsurprising that the mean return of 4.0c was below the long-term average by 0.6c. As a result of the above, can you guess which phenological indicators were to show themselves amidst the cold of January?
The first Primroses (Primula vulgaris) were witnessed in bloom on 5th January. However, before we jump for joy at seeing them so early in the year, one should perhaps, read an excerpt from Richard Mabey‘s wonderful Flora Britannica. In there, Richard states that they are not the most reliable of indicators when it comes to tracking climate change. Oh well! They are however, beautiful to see and always brighten up a dull day.
An early songster is always nice to hear and one of the first to embrace the New Year was the Blackbird (Turdus Merula). I first heard the 2013 song of this particular species on 7th January, whereas last year it was 9th January. A personal sound recording of a Blackbird can be heard below. This link will take you to another website, which upon opening, you should click the orange icon on the Left Hand side of your screen to allow playback of the sound recording.
The next phenology indicator of interest came courtesy of First Hazel Flowering (Corylus avellana) on 11th January. This compares favourably with the 7th Januarysighting from the previous year. A record shot of which, I have attached below.
The final phenologically related event of any consequence came about on the 21st January. This revealed itself in the form of a Chaffinch (Fringilla coelebs) first heard singing. The corresponding date last year was the 13th January. A personal sound recording of a Chaffinch singing is available via the link shown below.
A final way to view the ongoing trend in my datasets is to observe them in graphical format. Good news!
Represented below are the aforementioned sightings in such a manner. Please note each event recorded annually is represented as a day number and not in date format. The events have been logged, only during years, in which I managed to achieve a meaningful result. Please make what you will of the data.
Given the cold conditions of January and the fact that I have often been preoccupied in my personal life, things have been rather slow to unfold. February was to prove a different story.
* The year of ongoing drought quickly became the year it never stopped raining, officially 2nd wettest in Met Office recorded history.
Here are my latest offerings from my Phenological sightings.
I first witnessed a Pendunculate Oak (Quercus robur) in budburst on the 3rd April. This matches quite closely to last year’s date of 7th April but is well ahead of 2010’s date of 24th April. The average date on which this bud bursting happens is 14th April, based on a sample of 11 records. Another similar observation being European Larch (Larix decidua) seen leafing. Being the 6th April, it matches 2011’s date and is four days behind 2010. The average date for European Larch leafing comes out at 1st April. As to the reliability of the aforementioned sighting, it is often difficult to separate leafing from budburst, when it comes to European Larch. *However, my keen eye also allowed me to witness Ash (Fraxinus excelsior) in budburst on the 8th April.* This particular event was very early when compared with other years. 2011 being the 24th April and in 2010 it was later still at 6th May. If compared to the average, Ash budburst normally takes place around the 23rd April, albeit based on only seven personal records. A final tree related offering, arrived in the form of European Sycamore (Acer pseudoplatanus) budburst, which I observed for the first time on 9th April. This event ties in nicely against the average observation date, also of 9th April. Now on to some insect related phenomenon.
The 6th April saw a further two annual butterfly sightings with Speckled Wood (Pararge aegeria) and Orange-tip(Anthocharis cardamines) being seen. The Speckled Wood sighting tied in nicely with last year with the 8th April. The average date of first emergence returns the 15th April. As for the first Orange-tip sighting, this year’s emergence is remarkably consistent with last year’s date, the 7th April. Once again, the average date of first emergence returns a date very similar to that of the Speckled Wood in that it is 16th April. Both samples are very healthy at 16 and 18 years of data respectively. News on flowering plants and bird activity to follow. Interestingly, I have not to date, noted Garlic Mustard (Alliaria petiolata) in flower which happens to be the food plant for the caterpillar of the Orange-tip butterfly.
Flowering Wild Garlic (Allium ursinum) was to be in a very early state of emergence in the gloomy weather of yesterday (9th April). This particular event occurred on the 17th April last year and not until 9th May in 2010. I have noted the first emergence of flowering Wild Garlic on nine occasions and this year’s date is the earliest in that dataset. The more usual date for flowering Wild Garlic returns the 24th April. Now some birding activity at last.
Firstly, the birds are a-singing more and more each day now. Mind you, it is not just the singing, which is increasing, so too is the breeding activity. I am pleased to report that on the 5th April, I was fortunate enough to observe a Blackbird (Turdus merula) with food in its beak. The significance of this event of course being that it is most probably feeding young. If this is to be the case, this event is actually behind schedule with the 31st March being the more usual date, albeit based on a rather poor sample of garden records of 6 records. With Red Kites (Milvus milvus) appearing each day above our estate and a flyby Little Egret (Egretta garzetta) being recently added to the garden list, things ornithological wise are very good. Further news from a local woodland patch of mine were groups up 10 Hawfinches (Coccothraustes coccothraustes) seen feeding by other birders but personally, a new migrant arrival pleased me the most. The first returning Willow Warbler (Phylloscopus trochilus) heard singing came about on the 8th April. This event closely matched last year with 6th April being the date and the average returns the 8th April too.
