2023 was an abysmal year for undertaking wildlife checks in the latter months. These checks were required to be undertaken on dry days but the weather proved to be so changeable that they couldn’t be planned very far ahead. Dry windows suddenly emerged in a persistently wet forecast and arrangements to undertake them had to be made hastily. This led to problems finding volunteer help to form the teams at short notice. It also made it difficult to run them concurrently with our major site volunteer days as they competed against each other for the help required. This problematic weather pattern affected our 2023 bat survey in late summer as we not only experienced continuously wet days but also periods of high winds, two of the least favourable elements to encourage bat box occupancy. The weather also cooled dramatically adding another negative factor to the activity.
The bat box checks were therefore commenced with very low expectations of finding any bat occupants. It had a big impact on our results in terms of numbers of different species found but proved not to be a complete waste of effort as many boxes showed evidence of occupancy at some time even if they did not contain bats at the time of the survey. The results we achieved therefore, were disappointing compared to other years but showed us that occupancy overall was being maintained. Some of the results are shown below.
Volunteers capitalise on dry intervals to undertake the bat box surveys.
Aware of the short duration of each dry opportunity….
….the inspections were progressed as speedily as possible.
Every box in the wide area of local countryside was carefully inspected and the occupants recorded.
Team members worked together….
….to transport ladders over the long distances it was necessary to travel.
At the end of the final woodland survey and the last record is entered, the team members relaxed.
Due to the unfavourable weather conditions….
….only the hardy Common and Soprano Pipistrelles were found in the majority of boxes.
Most boxes however, were found to be full of droppings….
….indicating that they had been well-used prior to the onset of the bad weather.
Bats were present only in ones and twos in many of the boxes….
….making it initially appear their numbers were down on previous years.
Other boxes however, told a different story….
….and were found to contain clusters of up to seven.
This was still less than previous years when groups up to a dozen were often found.
The number of boxes occupied were similar to recent years….
…but the variety of species normally found….
….were sadly lacking.
It is hoped that the next season’s weather is significantly better and the number of species found are greater and include the rarer ones we have previously found in our boxes. The results overall were however, higher than we had anticipated in such unfavourable conditions.
Our dormouse checks this year followed a similar pattern but with much more warm, dry weather to capitalise on. We visited all sites at intervals from April until November. The checks revealed no dormice in residence in any of our boxes this year. This followed a similar national trend, as revealed in the People’s Trust for Endangered Species 2023 report on the state of Britain’s dormice. This document highlighted an alarming progressive decline in the country’s hazel dormouse population which since 2000 had seen a reduction of 70% in total numbers. This reduction which has been tracked by the National Dormouse Monitoring Programme into which our results are fed, was found to be mainly due to loss and degradation of natural habitat, climate change and less effective management being applied to hedgerows and woodlands. Despite these alarming figures, it is not a completely lost cause, as conservation work continues with volunteers and partner groups in an attempt to combat it. Habitat restoration and re-introduction of dormice in selected areas they have previously completely disappeared from is being attempted nationally, to give the species as much help as possible to survive.
All our dormouse box locations are in areas where we have previously seen them or detected a presence, so we will continue with our efforts in the hope of an improvement in our results. Our results this year indicated a growing wood mouse presence with the early season addition of many blue tit’s and great tit’s nests. The following pictures illustrate some of our findings.
The boxes were visited at monthly intervals when possible.
Occupancy of each was recorded. This one contained one of the many resident wood mice found.
These inspections were undertaken by working parties of licensed volunteers.
Each volunteer undertook a different role to make the operation proceed as smoothly as possible.
This box contained a wood mouse nest.
This one contained a nest of birds eggs.
A devoted bluetit mother remained firmly on her eggs in this box. She was disturbed as little as possible.
This box contained young chicks who were at a more advanced stage and obviously very hungry.
Young birds were found in many of the boxes in early summer.
These eight great tit youngsters were almost fully feathered. Once all birds nests were emptied after the birds had fledged, the nesting debris was removed so that they were available for dormouse occupancy again.
Inspections carried out in mid summer after the birds had vacated the boxes, found wood mice had moved into many of them.
Again, the occupants were treated delicately with as little disturbance as possible.
All boxes containing food stores were left intact to benefit the breeding mice.
Each member of the team worked together to ensure inspections were carried out as efficiently as possible.
This mouse was found having a meal in a food store.
Each finding was recorded….
….to create a comprehensive annual record of everything found.
Inspections undertaken at the end of the season found an increasing number of boxes occupied by wood mice….
….with a large number utilised for food storage….
….and new nests….
….to ensure the mice successfully survived the imminent winter conditions.
Once the final check was completed all results were collated and the data forwarded to the national database.
The barn owl boxes are mounted in suitable locations across the owl conservation area.
Each box is visited to check if breeding has occurred.
Eggs found with the first one already hatched.
This picture shows two healthy chicks found on an initial inspection. On the next visit they were found to have been predated and had vanished without trace.
Two dead partly grown barn owl chicks found in a box situated in a meadow that had recently been sprayed with herbicide by the landowner to remove ragwort.
Each young barn owl is handled very sensitively and gently returned to its box when recording is completed.
One of the boxes found where voles caught by the parent birds at night were left to sustain the youngsters during the day.
Boxes utilised regularly by barn owls within their home range.
Another swathe of vital greenfield habitat utilised by foraging barn owls in our conservation area is lost to development.
One of the first boxes visited this summer found these three occupants. Note the difference in their stages of development.
The next box had four very young barn owl chicks in.
On the same day this box was found with just a single but very healthy occupant.
Another box visited that day had one unhatched egg and four youngsters of varying sizes.
This box had two chicks occupying one side….
….and two on the other side, making a grand total of four very healthy youngsters.
One to four owls were found in most of our breeding boxes this year.
It has been one of our most successful years for young owl occupation of our boxes to date….
….with the majority of box locations visited revealing yet another family of barn owl chicks.
The age of each chick was recorded on the first visit….
….and an estimate was made of timing of the return visit to record them.
Due to the considerable variation in the ages of the youngsters found….
.…the sequence of return visits to record them at the required size….
….meant that the huge owl conservation area was required to be criss-crossed many times over several weeks.
This ensured that they were all dealt with at a stage they had grown sufficiently to be able to accurately record sex, development and age….
….whilst still being of a size that could easily be handled.
Even on the first visit some chicks were small, cute and downy….
….while others were already large enough to be dealt with immediately.
For these larger birds a very quick return was made.
Not all owls were pleased to see us on the second visit and were determined not to co-operate….
….but the authorised team gently took charge and each was meticulously recorded with an identification ring placed on its leg.
The team was formed of a sufficient number of people to carry all the equipment required over the large distances across fields.
In some boxes we found a number were almost full size and ready to fledge.
The larger the birds found, the more difficult they were to handle, but they were all recorded in the same way….
….but with a greater respect being given to their sharp talons.
The smaller chicks were more easily dealt with….
….and seemed to appreciate the smart leg bracelet we fitted.
When recording had finished, they were carefully placed back into their respective boxes.
It was ensured that all the birds were completely settled before we departed.
This one had its plumage almost completely in place, but still retained an amount of down beneath.
These siblings demonstrated their staggered development due to progressive egg hatching, with the oldest on the left and the youngest on the right.
On their return to the boxes, they usually scurried to the furthest corner….
….a little unsure if they were to be disturbed further….
….or whether they could once again relax.
They are without doubt one of the most beautiful of all the birds in our local countryside….
….and worthy of the considerable effort we expend to sustain their population.
Volunteers gather to tackle the clearance task.
This was an example of the floral display that resulted from the group work effort.
Each bird box was checked and cleaned.
The newly planted tree to replace the felled unsafe oak was checked.
The bulbs were progressively planted to increase the biodiversity richness of the area.
When established, the bluebells should provide a further boost to the attractiveness of the woodland and value to wildlife.
Water was transported in drums to site….
….and all trees and wildflower plugs were kept watered.
Volunteers gather on a Saturday morning to address the problem.
The tree saplings had surged in intensity this year and had to be removed.
It proved more difficult than it at first appeared, as their roots had quickly established themselves firmly in the ground….
….but eventually the task was achieved.
All boxes were checked, cleaned out and maintained.
The damaged boxes were removed…..
….and replacement boxes were provided in their place.
Each heavy box had to be carried up to box height….
….and securely fixed in position.
All this owl box activity was closely scrutinised by the indigenous wildlife population sharing the location with us.
This area was becoming increasingly more attractive to wildlife….
….due to the care and attention it was receiving from group volunteers.
Many hours are spent each year keeping the site in prime condition.
All volunteers engaged fully with their tasks….
.…and ensured each was completed satisfactorily.
However busy the volunteers were, time was always found to appreciate the surrounding natural environment.
This volunteer attention is increasingly benefitting the indigenous wildlife, like this slow worm witnessed on the site this year.
Our tractor volunteer began the huge task of cutting the meadow.
With such a huge area to tackle it took many hours to complete.
The college student volunteers methodically began tackling the task before them.
They progressed from one end of the meadow leaving the hay in lines for later collection.
Progressively, the work spread across the area.
Some students found time to enjoy the presence of the local wildlife.
A common toad seeks shelter from all the activity.
A caterpillar scurries to the sanctuary of some surrounding untouched habitat….
….and a shield bug observes all from a distance.
After the raking into rows, the hay was then transported to central stacks for eventual disposal.
Volunteers man a group publicity table.
The audience gather for the evenings events.
Leif then gave them an extremely interesting talk for the rest of the evening which was very well received.
In the intervals between, Leif sold his book that the talk was based on.
He personally signed all of the large number of copies sold.
The stall as it appeared after being set-up.
Volunteers took turns to demonstrate the work of the group to visitors.
The stall remained on display until 6.00pm when the Super Sunday event closed.
