The vital role of citizen science

Tony:

The best way to observe nature is to follow the changing seasons. I subscribe to many blogs, of which the Woodland Trust is one. Their latest post reblogged above, illustrates how many folk are becoming highly valued citizen scientists.

Dog rose – one of many species recorded by Nature’s Calendar enthusiasts

For the past 14 years, enthusiastic volunteers have been helping track changes in seasonal natural events through Nature’s Calendar, adding thousands of records to the UK Phenology Network database. Faithfully, they have observed and recorded when trees come into leaf or flower in spring, when migrant birds arrive and leave, and have spent their autumn days noting when leaves change colour, then fall, or when fruit ripens. The data is being used by students and scientists across the UK, and even further afield, to research the implications of climate change for our natural world.

These recorders are part of a tradition that goes back much further, starting with Robert Marsham, who began recording his ‘Indications of Spring’ back in 1736 on his family estate near Norwich, Norfolk, and continued to record for 62 years. From 1875…

Bird Surveys, ill health and horrendous weather

Why the hiatus, I hear you ask. Well, let me explain if I may.

My current job role as a Bird Surveyor/Researcher allows me to intimately follow our feathered friends and log their breeding success. To best illustrate the differing roles out there, I will direct you to a couple of blogs. For example, Lewis Yates, whose exploits this birding season come from Skomer in Wales? Another equally interesting blogging view of things is available from Annette Fayet’s blog from the same Island. Who knows, maybe I will start a blog covering my exploits one day in the future too. As well as my fortunate paid position, I have been putting my experience to good use for the following survey, which is tracking Nightingales (Luscinia megarhynchos) as shown here. In fact, having previously referred to my volunteering exploits, I would say there is no better way for improving your self-esteem.

Due to the busy schedule, I may have suffered a bit of burn out in recent weeks, which resulted in a cold and finally horrible chest pains. Sparing you any further details on that particular subject, I must say the recent weather has not exactly helped my cause, either. Since my last phenology related post, I would say I have added another 25 or so events. Eighteen having Ornithology as a background theme, a further four, flora related, two strictly weather related and the final one having an insect theme.

Insect sightings from Mid April to the end of the first third of May

Only the one addition being a First Holly Blue butterfly (Celastrina argiolus) was in the form of a flying individual during the brighter spells of 30th April. Based on a useful sample of 17 records, the usual flying date is 26th April. 

Thunder days since the last update

At Newbury, Berkshire we bore witness to another 2 Thunder days, making these the fourth and fifth respectively. The dates concerned were 19th April and 22nd April. Considering the more usual period for these phenomena (fourth and fifth dates of Thunder) covers the period between 30th June and 11th July, it does seem exceptionally stormy this season so far.

Trees and similar things from Mid April to the end of first third of May

During Mid April, I truly believed trees were budding and leafing well ahead of schedule, has this since changed?

Pendunculate Oak (Quercus robur) was first observed leafing on 23rd April and subsequently Beech (Fagus  sylvatica) budburst was on the 9th May. So how do these events appear in the general scheme of things?  Their averages based albeit on small samples, cover 19th April and 14th April respectively. So there is a clear difference between the timing of the two events with it seems, the colder April weather having particularly affected the Beech. With regard to flowering trees and shrubs, Horse Chestnut (Aesculus hippocastanum) was flowering on 22nd April, which compares to its normal emergence date of 27th April. Hawthorn (Crataegus) being first observed flowering on 8th May, near to its average date of 5th May.
 
Bird sightings from Mid April to the end of the first third of May
 
Seven down, Eighteen to go. Okay, to save this post from being too long-winded, I will only inform you of local events. After all, the birds on our own patch are of most interest!
 
Back on the 18th April, I had my first sighting of a House Martin (Delichon urbicum), matching well with the more usual date of 17th April. The local Nightingales (Luscinia megarhynchos) came next when heard singing on the 22nd April. With a healthy sample of 14 years of records, you can normally expect this event around the 28th April. Come the 27th April, I recorded a Common Whitethroat (Sylvia communis), Garden Warbler (Sylvia borin) and a Common Redstart (Phoenicurus phoenicurus) all for the first time on a local level. The respective mean dates work out at 23rd April (Whitethroat), 29th April (Garden Warbler) and 18th April (Redstart). The Redstart is a case in point for a lack of records, although as it is a rare bird in Berkshire, even on passage, I should not be disheartened. The 27th April saw the arrival of young Blackbirds (Turdus merula) in my neighbourhood for the first time this year. The mean expected date for these being the 21st April, so I would say it was feasible that some Blackbird have seen their first broods fail. The 29th April proved a rare day out for me, with a trip to the River Kennet. There, in the space of no more than five minutes, I came across firsts in the form of Sedge Warbler (Acrocephalus schoenobaenus), Common Swift (Apus apus) and Hobby (Falco subbuteo). The Sedge Warbler proved to be a bit later than is usual with its average date being 20th April. The Hobby witnessed dashing ferociously at the Swifts does represent a smaller sample with an average arrival date of 28th April. Likewise, the Swift shows a similar expected arrival date of 30th April.
 
Finally, the 7th May brought about some more young bird activity to my garden in the form of Common Starlings (Sturnus vulgaris). To this end, I can be extremely proud of myself having witnessed the first nest building of Starling on the 29th March. A whole 39 days later, it is just possible I witnessed the return of the same bird and its fledglings. Is this a careless assumption? Is there any significance to the quoted dates? Hell yes! The B.T.O’s Field Guide to Monitoring Nests suggests a period of 38-40 days from the end of actual nest building to free-flying young. You do the math! From my phenology record point of view, these young Starlings were observed 10 days earlier than in 2011 and are more normally seen for the first time around the 18th May.
 
 
My only other sightings relate to non-local events and are of limited interest at this time. I look forward to updating you further in the busy days and weeks ahead. Being back to full health, I will have no excuses and with this dull weather hopefully in the past, there will be many more tales to tell.
 
Best Wishes

Volunteering – Do you participate?

Do you volunteer? 

If not, would you consider doing so?

I have been volunteering in many guises over the years, but more recently I have become a WeBS counter. This is a survey organised by the BTO (British Trust for Ornithology) which covers a broad spectrum of wetland bird species. The surveys cover a large area of UK wetland habitats, currently approximately 2,300 in number. The counts are carried out by volunteers, who visit the sites through November to March, although some of which are visited all year round.

Yesterday (20th November) was my 2nd visit this season, to a local gravel pit complex where I undertake my count. These counts provide an invaluable dataset for the BTO researchers and it’s yet another good example of citizen science in action. Being a data geek, I look forward to the WeBS reports when they are issued to me as a participant. Over many years, trends become apparent in the statuses of the birds, although I would say too early to find them in my own data. Nevertheless, these trips to the local patch open my eyes as to what is out there to be seen. Furthermore, these additional efforts look good on my CV, in turn allowing further progress towards my career in conservation.

Happy Birding

I’m obsessed

It must be said, I am obsessed with participating in Citizen Science. This might take the form of listing garden birds, a local patch list or trips farther afield. Maybe, it’s the daily transfer of weather records from my diaries, except this is not necessary any longer, due to owning an AWS (automatic weather station). Perhaps, as in today’s instance it’s keeping track of Phenological indicators and yes, in spite of it being November, there can be some events at this time of season. I take immense pleasure from “doing my bit” and it can feel like one’s been “warped back into time” when browsing over those personal snippets of information. Today, as in many recent weeks, I’ve been doing just that and it must be a most valuable way of spending my quiet unemployed time. You can also learn so much from the actual interpretation of your data, the deeper you delve.

Right, to put an end to my current rambling, I have up to today (11th November) , entered approximately 54 Phenology events onto Google Calendar and these can seen in My natural events calendar on this blog. This enables me and others, should they wish, to track and compare progress of the seasons in further intimate detail. After all, the purpose of this blog is just this.

  • I will endeavour to produce a timeline of natural events for the United Kingdom like no other

I will attempt to elaborate on each of the events, as they unfold, over the course of the climatic season. Hopefully then it will be possible to then explain their reasoning’s for happening on a given date. Learning from this, we may be able to ask why the phenological event differs from others within the dataset. How they may or may not then be used to forecast forthcoming weather etc.

Science in this subject is still in its relative infancy and this is precisely why I feel the need to explore my own records.
