No pollinators = No Sloes for Sloe Gin.
109 species of insect are associated with Blackthorn , including the rare Black Hair Streak Butterfly. As an early native flowering hedgerow plant, Blackthorn provides valuable nectar and pollen for bees and other pollinators. The foliage which appears after the flowers is food for many moth caterpillars. Birds, including Nightingales and Blackbirds nest within the thorny dense thickets and as part of the food web, eat the caterpillars and other insects on the leaves. Birds also feast on the sloe berries in the Autumn.
Salix caprea – excellent early source of pollen and nectar for all pollinators. Drone Fly, only one pair of wings, 10-12mm long body, large eyes and inconspicuous antennae. Drinks nectar, visually mimics male honeybees hence common name.
The first Wednesday of March, one day after the beginning of our meteorological Spring is suddenly here. February flew by in a blur. The weather has veered from heavy rain and high winds to occasional sunshine and sharp frosty mornings.
The cold weather brought in a trio of Goldfinches, to feast on the seed heads of Rudbeckia, Teasels and Astilbe. The males and females are similar but females are slightly duller with less red on their face; the trio looked masculine. And made me glad I had not cut back any of the overwintering seed heads, despite the untidiness and my itchy fingers.
We kept warm by spending a whole week digging out the rocks and soil of an enormous ground elder, riddled and inherited rockery, most of which was wheelbarrowed into a large skip. As the drab brown sandstone rocks were dismantled, we discovered family groups of snails. As the food of Thrushes, snails always remind me of Summer and listening to the ‘tap, tap, tap’ of a Thrush as the snail shell is bashed on something hard to reveal its contents – one of my favourite summer sounds.
The larger mature snails hibernate during winter months and waken up in Spring. Mostly they were still dormant but one brave small snail began to explore. Shortly they will become more active especially on cloudy or rainy days, they dislike desiccating hot sun.
Underneath the snail, which at it’s fastest is reported to travel 1.3 centimetres per second is a ‘foot’, a flatish muscular organ. Mucus is released to help the snail glide over rough surfaces, leaving a tell tale meandering trail. Apparently they have a complicated and interesting sex life and can produce 430 babies a year. On the upside they are one of natures cleaners, consuming debris, sadly they are also partial to a prized vegetable leaf. As well as Thrushes – Ducks, Lizards and Frogs eat snails. We’ve cleared the rockery area to make space for a recycled greenhouse and small pond with wildlife friendly planting where we hope visiting Frogs, Wild Ducks and Thrushes will have a field day on the snails.
Since my last Wildlife Wednesday post on our Robins, we haven’t seen any sign of nesting (yet) but the poor little Dunnocks, subject of many a Robin attack are nest building in one of our wood stores. This little brown bird also has an interesting sex life and pair up in unusual and complex ways. In their determination to carry on their gene pool, they can pair male and female, one male two females, one female two males and several males and several females. All very liberal!
Hopefully when you read this, you are not eating. Often two males mate with one female , the female hopes both males will help her raise the chicks. The dominant male will try to remove the rivals sperm by pecking the female’s rear end (the cloaca – through which both faeces and eggs exit) and encourage her to eject it. Dominant male mating then follows. Liberal and ghastly!
Less complicated are our Blackbirds, this fellow is singing his heart out. The Black Feathered males with bright yellow bills and eye rings are easily identified. Juveniles are similar to females, the RSPB explain how to identify the juvenile male wing bars.
We are quite hopeful there is a Blackbird nest just beyond our vegetable garden in an area of overgrown brambles, grasses and emerging wildflowers with pioneer native Alders growing along the drainage ditch and Birch trees colonising the bare areas. Both tree species will be rich in insect life, for the birds to forage on. Technically this area is a no mans land, land locked between houses and fields with no hope of future access. Many a snail and slug has been delivered here, for foraging creatures further up the food chain.
And finally on a more colourful note, this last photo was taken on Sunday morning in the RHS Wisley Garden, I had a couple of hours to while away waiting for my daughter to finish her netball training. As I leant forward to smell the fragrance of the Edgeworthia, a very round Robin hoped onto the branch, inches away from my face, one of those uplifting and life affirming moments. There is a great deal to worry about in life but there is also a great deal to be grateful for and enjoy in the natural world.
With many thanks as always to the lovely Tina and her wonderful Wildlife Wednesday meme, please take a look at other contributions from across the globe.
Happy Wildlife Watching!
Berberis darwinii can provide a good protective nesting site, within its dense thorny branches for birds. The flowers provide nectar and pollen for pollinators. Autumn berries provide food for birds.
Packing a powerful fragrance, three forms of Sarcoccoca in the Anglesea Abbey Winter Garden providing pollen and nectar for awakening Queen Bumbles and other Pollinators.
Nectar and Pollen maybe taken by Blackcaps, Bluetits and House Sparrow. Berries eaten by Blackbirds and Mistle Thrushes. Early flowering nectar source for Bees and Bumblebees. Bright Line Brown Eye, Cabbage and Peppered Moth Caterpillar Food Plant. Non-native introduced to UK in 1823.
We have two Robins visit our garden, one is currently rotund, one is svelte. Apart from girth neither of our visitors have any distinguishing marks. Male and females are almost identical. Usually breeding begins in March with the first clutch laid in April but our mild winter will probably lead to an earlier courtship. I’ve read that females require more body weight for producing eggs, so I have fingers crossed that Rotund is a female.
In colder weather both sexes plump up their feathers for insulation and warmth, but when seen at the same time, its clear one is much rounder than the other. So far, there’s no activity in the nest box but Robins create nests in all sorts of odd places, we are fairly sure there is activity in the potting shed, mainly due to the additional droppings on the potting bench. But what’s a little poop between a gardener and her friends!
Renown as territorial birds, both males and females defend their individual patches all year round and once united defend their joint territory for the summer months, parting after their chicks fledge. Last week we watched Svelte defending his territory, eyes to the sky, he had heard the incomer before us and was waiting for the newbie to land, but he wasn’t really aggressive and believe it could have been Rotund landing on the table.
There wasn’t a fight as such, just a baring of his Red Breast, which we read they only do to defend territory, however we have also read in our well thumbed RSPB ‘Handbook of British Birds’, that Robins “have elaborate courtship displays when the red breast of the male is used as a visual signal to attract females and deter males”. Either way, the newcomer hopped off.
I couldn’t quite make out what was being said here, but following the encounter Svelte let out a cry of frustration/warning/who knows? The following day Newcomer came back again to try his/her luck, Svelte postured with head high and lots of red breast baring, despite the wind blowing his feathers apart. We could see no real aggression and the 2nd bird crouched on the ground watching quietly.
Newcomer remained crouched on the ground watching Svelte posture about for a few minutes, Svelte then turned tail and Newcomer flew after him. I’ve read of fights to the death and just hope they both came to a gentleman’s agreement, but nature can be cruel and the brutal fights part of life’s cycle.
(Or as the RSPB book suggests, this is maybe courtship and Newcomer is actually Rotund – her crouching down is the mimicking of a chick and they were off to the bushes for some privacy? – time will tell.) Males chase females from their territories for some days until finally the male accepts her and they become a couple.
Some while later, a slim Robin we assume was Svelte resumed feeding, happy to share fatballs with Blue Tits. Robins are only territorial with their own kind and the only birds we see being chased off are the dowdy, timid ground feeding Dunnocks.
If we do have a couple, there will be courtship feeding – the male feeds the female, apparently its a prominent activity, we are desperately hoping to see this and then will know for sure if who is male and who is female. The male can supply over a third of his mates food intake during nest building and egg laying. She alone is the creator of a cup shaped nest, made of dead leaves and moss, lined with hair. To help her we have saved our Labrador’s soft underbelly hair for months and have placed the soft hair in a mesh feeder ready for all nest builders.
The RSPB report that the parental instinct in Robins is highly developed and they are known to feed the chicks and fledglings of other bird species, including Song Thushes, Blackbirds, Spotted Flycatchers and Willow Warblers, the latter two we do not see but we have had Blackbirds nest in our garden. I guess Robins would only be able to step in if they had no brood of their own. We would be thrilled if these two were a couple and over the moon if there were nesting, egg laying and hopefully successful fledgelings.
I’m joining in with Tina’s My Gardener Says meme Wildlife Wednesday, where lots of other folk from across the globe are sharing their wildlife experiences.
Happy Wildlife Wednesday!
