Just when I think there is nothing more to be gleaned from our Joseph Rock Rowan, a beautiful and acrobatic pair of Bullfinches turn up and expertly gather some of the last, now bletted but obviously still nutritious berries from the very tips of slender stems. As the tree is about 15 feet away from the window, the views, in yesterday’s welcome sun, were clear and bright. We have two pairs visiting at present, which I know is very lucky- a function of being near a wooded part of Sheffield centre and the fact that we plant for wildlife and feed all year round. Conditions: a welcome spell of calmer, brighter weather. Temperature: Max 10 Min 8C.
Robins in winter– Robins are one of a few birds that sing throughout winter in the uk. This is because they are particularly active in defending a territory year round but scientists in Bristol believe that us feeding Robins through the winter helps. Birds have a complex mechanism to manage their fat reserves, and Robins will only sing through the winter if they are well fed enough. They appear to be able to assess when they have enough energy to sing in the day, so a ready supply of food, and warmer nights means they are more likely to be heard defending their territory by their beautiful song
. Another reason to feed our birds. Conditions: A spell of bright, sunny weather. Temperature: Max 6 Min 3C.
Kestrels: Once our most numerous bird of prey, Kestrels have declined and Buzzards have increased and are now number one! Yesterday when, taking our van out for a run, it broke down (sorted by rescue). We were therefore delighted when this one flew in near the lane we parked up on. Kestrels use high perches to hunt from, especially in winter when they need to preserve energy, as their characteristic hovering uses far more energy. This one didn’t stay long, so we occupied ourselves waiting for roadside rescue by playing scrabble we had in the van, but it was lovely to watch this one, probably looking out for a small rodent, like a vole, by far their most frequent food source, though they will eat earthworms, large insects, even sparrows in cities. Kestrels were
reserved for the lower status Knaves in medieval falconry, larger hawks being reserved for Knights. Hieararchies have been around for a very long time! Conditions: Another frosty, bright, dray day. Temperature: Max 2 Min 0C.
Mallard numbers are increasing and you can see them on almost any stretch of water, in fact they may be becoming a bit too dominant but nevertheless, they are worth watching. I have covered a few birds washing habits this year and non is more enthusiastic in its dunking style than the Mallard. Also, watch out for them ‘asleep’. They can sleep with one eye open, meaning one brain hemisphere is alert while the other sleeps. Not a bad adaptive behaviour! Conditions: More grey, damp days. Temperature: Max 9 Min 2C.
Winter Thrushes– a survey of the six members of our Thrush family took place at the beginning of this decade. The six members are: Blackbird, Song Thrush, Mistle Thrush, Ring Ouzel, and the winter visitors from Scandinavia, Europe and Iceland, the Redwing and Fieldfare. All species have shown a decline in the last forty years We have begun to see a few of the winter visitors among our resident population of Song and Mistle Thrush, and Blackbird in the garden. All love the berries on our ‘Joseph Rock’ Rowan. One of the findings of the survey bears out the importance of all berries, including Ivy, for the Thrush family in autumn and winter: feeding on trees and bushes begins to reduce around now, as fruits and berries decline, in favour of ground feeding, where all these birds can be seen rummaging around in the topsoil and turning over leaves to expose worms, Snails and invertebrates so plant trees and shrubs with late berries, keep the Ivy growing up a wall, tree or hedge, let it flower and berry, and don’t pick up all the leaves as they make a microclimate for insects and
bugs which feed our winter birds. Conditions: Dank, drab days of rain and cloud. Temperature: Max 11 Min 7C.
Overwintering Blackcaps– Yesterday was a first for us in our Sheffield garden- not that we had overwintering Blackcap, as we do see them eating berries in the garden most winters now, but that we had this female Blackcap (only males have a black cap) feeding from our fat-filled coconut and off the scraps that fell from a Great Spotted Woodpecker feeding messily on fat. It is only since the 1960’s that this warbler, known colloquially as the ‘Northern Nightingale’ because of its beautiful,
melodious song, has been seen overwintering in the UK and it is thought that one main case is the food we now put out in so many areas of the country. This new pattern is predicted as eventually evolving it into a separate species from those that overwinter in Spain. Conditions: Thick cloud and rain showers. Temperature: Max 8 Min6C.
The light wasn’t great for photo’s when the Redwing, the female Blackcap and the female Parakeet turned up over the last few days to feast on what remains of the yellow berries on our Joseph Rock Rowan but the presence of such a range of birds drawn into the garden by one late-berrying tree like this really shows its value, even whe
n the brilliantly coloured autumn leaves have been blown away (thanks to recent Northerly winds, not all into our garden !). Any birds arriving now have to be acrobatic, as the only berries left are at the extreme tips of the boughs. Blackbirds manage it but not much else. Conditions: A welcome dry spell, with a frost on Monday night. Temperature: Max 6 Min 1C.
