Sorry people but for those interested, I have a new blog up and running called UKbirdingtimeline, which can be accessed from here or via the home page. This blog will run in conjunction with naturestimeline.
I would just like to bring to your attention, the latest posting from over there.
My regular readers will know that I painstakingly (too strong an emotive really) update my phenology calendar to reflect on the natural events taking place in the United Kingdom. So, now that the mixed spring has passed, what effect did it have on nature, more especially our familiar breeding garden birds?
When it comes to young birds, my garden attracts many different species and these are a few examples. Bear in mind, this list is not exhaustive and further additions may become apparent in time.
When I first witnessed a juvenile Dunnock and a juvenile Chaffinch on the 18th May, the weather was still grim with winds from the northeast as can be seen below.
As we are meteorologically speaking, now in the season of summer, let us look back at spring 2012. On reflection, do you feel it was a pleasant one, weather wise for the United Kingdom? As ever, courtesy of my Davis weather station, I can add some meat to the bones to my previous question.
Spring 2012 (March-May) was at its traditional best overall, although with a notable exception here and there. Look at the following plot for a closer view of Newbury, Berkshire’s Maximum Temperatures and Rainfall amounts.
From the above, it becomes apparent that 2012 proved a mixed bag. Indeed, the local climate changed abruptly on occasions. Take for example, the March rainfall deficit of 29.2mm when compared to the 30-year local average of 50mm. All the talk in the media at this stage was of impending drought and hosepipe bans. However, as most will be aware, April changed all that. Some of this, at least at a local level dramatically changed with a huge surplus of 61mm by the end of the month. May then ended up drier than usual with a deficit of 14.3mm when compared to the local 30-year average. What about the temperatures I hear you ask!
For your information, the 30-year mean temperature averages (Oxford 1971-2000) are as follows. March normally returns 6.3c, April 8.1c and May 11.3c with regard to expected temperatures. Please bear in mind, the figures shown in the above plot only show our achieved maximum temperatures. When mentioning the aforementioned averages, the weather station automatically calculates these against mean minimums and maximums so I don’t have to do the mathematics. Using the plot above you can now analyse the 2012 spring season further with regard to its temperature.
March, with a very warm finish ended 1.6c above the mean. April abruptly turned the warmth to cold with a temperature return 0.8c below the mean. Finally, May 2012 warmed up, especially in the final third to return a local mean, 1.2c above the norm. I attach a final summary below confirming the above figures.
As for the effect on phenology, further news will be forthcoming.
