times, periods, emergent, damselfly
...
Recently, after a quick search of the web, I couldn't find an easy reference with all the dragonfly (and damselfly) emergence and flight times on one page. So I decided to make one.
The light blue represents the start and finish of the flight time for each species, with the dark blue being the main flight period. I used Smallshire and Walsh (2004) as the source of this infomation.
The table itself should be used as a guide, rather than an exact calender, since dragonfly emergence and flight times vary due to weather and where you are in the UK with emergence times tending to be later the further north you are. Climate change appears to be affecting emergent times too, with milder winters leading to early emergences and flight times continuing into late autumn.
Happy dragonfly (and damselfly) hunting!

After the success of the Britain’s commonest bird post, I thought I’d tackle Britain’s commonest mammal. Finding out the exact population numbers for the mammals found in Britain is a difficult process, due to the secretive and often nocturnal habits of most the mammal species. Due to this some of the numbers have been estimated by recording the density of a species in the habitats in which it occurs and their total population extrapolated by multiplying the density by area of each habitat. This, combined with other factors such lack of recording, has led to some species population estimates being correct only in their broad ranking or even only to the right order of magnitude in some cases. Despite these difficulties population estimates have been published and I have used those from DEFRA’s website in order to create a list of the top five most common mammals in Britain, which is as follows:

Nearly a month ago I took a mammal course at Wildwood Trust in Kent, which is where all the bones and skull photos come from. It had snowed that weekend, so as we walked around after the presentation I got some photos of the residents in the snow. The fallow deer seemed to be comfortable in the snow

Here is there rest of my report from Monday. This a very photo heavy post, so give your browser a chance! After leaving the chase I crossed the road and entered Harrow Lodge Park. Heading towards the lake I saw a Jay and a greater spotted woodpecker on the same tree with a green woodpecker below! When I got to the lake there was a very cooperative Black headed gull stting on a pole

When is a fly not a fly? Many insects are referred to as ‘flies’ but technically any insect that doesn’t belong to the Order Diptera, is not a true fly. Below is a brief summary of the groups found in Britain that are referred to as flies:

After the question of what is
Britains biggest bird, I thought I'd ask and answer another question: What is Britains commonest bird? The first set of data I have used is that based on numbers of breeding pairs or breeding territories. This is because the actual number of each bird species in the UK rises and falls depending on the time of year due to migrations, breeding and deaths in winter etc, so the number of breeding pairs gives a clearer picture of the true abundance of each species. I also used this data as it is easily accessible on the
RSPB website The top 10 most common British birds are:
