Breeding Birds on the Farm in 2022

In the heart of rolling Dorset, you can find my family’s home, a 250 acre mixed dairy farm with the hope of producing food alongside conserving and promoting nature. As a naturalist and conservationist, the farm is my base for exploring, learning and putting ideas into practice. With an increasing variety of habitats, there is an increasing amount of wildlife to experience, explore and enjoy, in particular a fantastic diversity and abundance of bird species (explore my blog for more adventures).

In 2019, I got the opportunity to begin training as a bird ringer with a local trainer, which was one skill that I always wanted to gain. Whilst working towards gaining my next permit, a C permit, my training has allowed me to acquire greater knowledge and a new perspective of the birds that call my family’s farm home. In 2022, my C permit was in reach and my training gave me some new experiences and some continued fantastic moments. Whilst the breeding season for birds currently plays out for 2023, I want to look back on my experiences for 2022 to see what can be learnt, including our amazing barn owls.

Kestrels

In previous years on the farm, we have known kestrels have been breeding here, but not where they were nesting. In 2021, we did find one nest within a hole in an ash tree, where a pair hatched 3 chicks. Two weeks later though, at the end of June that year, bad weather unfortunately led to the chicks not surviving, potentially due to the nest being exposed to the harsh weather. Thankfully in 2022, this same hole was used again by a pair of kestrels, and they successfully reared 3 chicks fledging in the first week of July, and I was lucky to have the opportunity to ring them too.

I was as well lucky enough to discover another pair of kestrels nesting in a hole in an oak tree at the other end of the farm. This pair was also successful, raising 4 chicks to fledging in the second week of July, that again I got to ring when they were still in the nest. With spring having been odd this year, kestrels are late breeding, so it will be interesting to see how it plays out for them.

Swallows

Year-on-year, the swallows return to nest within our farm buildings and our neighbour’s outbuildings, and still do so even if population numbers are not as high as they used to be. For 2022, I began my nest checks of the two properties as part of my ringing training on the 25th May. During this check I found 5 nests in use, with one already containing eggs. These 5 eggs hatched on the 27th May, and marked the start of a rocky breeding season for the swallows. With the first round of nests, 4 nests got to the chick stage, but only 2 fledged chicks (3 and 5 respectively). One of these nests then successfully went on to rear another brood of 4 chicks to fledging, though most pairs did not re-nest as the weather was very hot and dry last summer. Fingers crossed for a better year this year!

Barn Owls

Barn owls go hand-in-hand with my family’s farm, so it is unsurprising that they are my father’s favourite bird species. With our nest box being a popular site each year, since 2019, barn owl chicks have been ringed on the farm by my ringing group, even before I started with my own ringing training. In 2021, Barn owls had a tough year though, with bad weather having an impact on their success rate on the farm. Thankfully in 2022 they had more luck, with a pair nesting in our box hatching 5 chicks, varying in size, at the end of June. They went on to successfully fledge 2 chicks. The icing on the cake was discovering another barn owl pair nesting in a hole in the ash tree also used by one of our kestrel pairs. These particular barn owls hatched eggs at the beginning of June, and went on to fledge 2 chicks too. Fantastic!

Garden Visitors

In 2022, as I worked towards finishing my training to get my bird ringing C permit, I got to do 2 days of ringing in my garden for the very first time. Though fairly small, our garden is a hub of avian activity daily, so I was excited to see what mist nets would catch. On the first day we caught 100 new birds (30 house sparrows, 30 great tits, 23 blue tits, 7 starlings, 4 chaffinches, 2 robins, 2 blackbirds, and 2 great-spotted woodpeckers), with a lot being juveniles. On the second day, 2 1/2 weeks later, a morning spent mist netting caught another 101 birds, with 92 being new (33 blue tits, 33 house sparrows, 7 great tits, 4 chaffinches, 3 robins, 3 great-spotted woodpeckers, 1 blackbird, and 1 goldfinch). It was really interesting to get the opportunity to get an idea of how many birds there really are in my area and producing young each year. Apparently alot!

All birds were ringed under license and following rules to ensure the health and welfare of the birds handled.

I look forward to seeing what 2023 will shape up to be!

26 Years of the BTO’s Garden BirdWatch: Getting Involved During Lockdown

As winter creeps into the landscape and a second lockdown keeps us close to home, our gardens are once again coming alive. Wrens creep through the undergrowth catching insects, Robins sing to defend small territories, and Long-Tailed Tits flit between hedgerows foraging in family groups. It’s not just the birds though, other species are settling down to see out the winter in our gardens too, from butterflies and toads to hedgehogs and ladybirds.

With this year being a bit different, I have found it a great time to take part in the BTO’s Garden BirdWatch, to further connect with nature, boost my mental health, and do my bit. Gardens are very important homes for wildlife, not just at this time of year, so now is an important time for us to understand how we can better help the wildlife that share our gardens with us. If you have a bit of time on your hands, want to do something a bit different, or are interested in the wildlife on your doorstep, then this survey could be just what you need!

The BTO and the Garden BirdWatch

So, what is the BTO? Well, the BTO stands for the British Trust for Ornithology, where ornithology refers to the study of birds. Started in Oxford in 1933, this now Norfolk-based charity aims to engage people with science whilst advancing the understanding of birds and now other wildlife species. With over 60,000 dedicated volunteers, and projects ranging from bird ringing and Cuckoo tracking to urban gull and bat surveys, the BTO has gone from strength-to-strength.

Set up in 1995, one popular BTO project has been the Garden Birdwatch, a project aiming to understand the relationship between wildlife species and our gardens, and how and why some of these species populations may be undergoing change. In a nutshell, the Garden BirdWatch is about participants recording the birds they see in their garden, along with mammals, amphibians, reptiles, butterflies, bumblebees, and dragonflies. As vital habitat for wildlife continues to decrease, whilst the importance of gardens as substitute habitat increases, the information we can provide now can be used to better tailor help to support wildlife in the future.

So why should you take part? Well, the Garden BirdWatch is a great way to enjoy the wildlife in your garden, improve your knowledge, and allow you to follow the annual cycle of life. Taking part is also easy! All you need is a garden, a minimum of 20 minutes a week, and a way to identify the species you see. You do not need to have a big or elaborate garden, put food out, or be an expert. With the Garden BirdWatch currently being free for a year, signing up is easy. Provide a few details about your garden, and get started recording the garden birds and other wildlife that visit you.

Why not join thousands of other volunteers today, and do something new from the comfort of your own home!

Examples of Results

Last year marked the 25th year of the Garden BirdWatch, and so the BTO have now been able to use 25 years of weekly garden observations to begin analysing the relationship between our gardens and wildlife. For example:

  • Goldfinches, Woodpigeons, Nuthatches, and Jackdaws have become an increasingly common sight in our gardens, relying on our gardens for vital foraging habitat
  • Song Thrushes, Greenfinches, Starlings, and House Sparrows have become a less common sight in our gardens since 1995, due to a range of factors from disease to loss of habitat

I have now been taking part in the BTO’s Garden BirdWatch for the last 21 weeks. This time has gone past so fast, but has opened my mind to the diversity and abundance of species that visit my garden through the seasons. To sum up my time so far, here are some of my results:

  • I have observed 26 different bird species in my garden, with the most abundant species being Starlings (50 on 28th July) and House Sparrows (40 on 28th July), followed by Goldfinches (30 on 1st October)
  • Every week Blue Tits, Great Tits, Collared Doves, Pheasants, Goldfinches, and House Sparrows have been consistently recorded
  • As summer has moved into autumn and winter, Coal Tits, Jackdaws, and flocks of Goldfinches have become newly reliant on my garden, whereas Great-Spotted Woodpeckers, flocks of House Sparrows, Pheasants, flocks of Starlings, and Sparrowhawks have decreased their visits
  • No week or month has been the same, with summer highlights including Greenfinches, Siskins, Chiffchaffs, and Garden Warblers!

So, why not see what wildlife you can encounter this winter?

An unexpected and unusual food source

Throughout July, we noticed an increasing number of birds spending time in the vicinity of our farm’s slurry store (large open-topped tank above the ground). Consequently I decided to investigate the reason for this.

The birds numerously seen were flocks of starlings, flocks of house sparrows and a couple of our local black-headed gulls (one in particular was seen everyday, which we named Nigel). From the outside of the slurry store, you could see the birds perching on the edge of the tank and at times flying down inside, often to not be seen for a few minutes.

To take a closer look, I climbed up the ladder on the side of the tank to get to the platform which would allow me to look down into the store.

On this platform, you could look all the way to the bottom of the tank, which during July had only a couple of feet of slurry left within it. From the platform I was able to watch the behaviour of the birds without disturbing the birds . Consequently my suspicions about what the birds were doing were soon confirmed.

All the birds spotted, were exploiting the slurry store as a location to find food, such as feeding on fly larvae hatching in the surface of the slurry. All these different bird species had different strategies to feed in this environment. House sparrows would fly down to the bottom of the tank, to pick larvae from the surface of the slurry whilst on the wing. Starlings would perch on the nuts on the inside of the tank’s walls, before flying down to pick off larvae or hunt on the surface of the slurry. Black-headed gulls would use similar tactics, but would often sit on the surface of the slurry where it was most watery and feed at their leisure.

It was very interesting to watch these birds feed, but now into August these birds have moved off to exploit other further food sources.
