Back
at the end of October, on the first day of the clocks going back, I
was consciously staying outside in the garden to make the most of the
abruptly shortened daylight. The clock change tends to throw you into
the winter overnight but that particular evening, as the light began
to fade, I had a most unexpected surprise from the natural world. I
heard a bird singing that I’d never expect to hear before late
February at the earliest. A Blackbird was piping out a lovely soft melody,
a song that’s ubiquitous during spring and early summer but here
it was singing at the beginning of winter. I didn’t totally believe
my ears so looked hard to spot it in the gloom and eventually saw it,
singing from a neighbour’s cherry tree, his pitch black plumage
surrounded by the amber and orange colours of the autumnal leaves. He
came into my garden and continued singing for the next two weeks, singing
at dusk. Why was a bird that should begin singing as spring starts be singing as we’re about to enter winter? Since so much of bird’s behaviour is determined by day length rather than weather it’s probable that a day in late October would be around the same length as a day in March which might have triggered it to declare his territory. Probably a total waste of time for him but it gave a lovely hint of spring time to come when the dark days have passed. |

It
is recommended that nest boxes be cleaned out of old nest material.
This is to prevent parasites breeding in them as these might infest
new born chicks next time it is occupied. Another reason to empty the
box is so a bird prospecting for a nest doesn’t think another
bird is already nesting in it. I’d left it too late to empty my
Blue Tit nest box last winter and it was occupied earlier than usual
in the year so it never got cleaned out. I was determined to clean it
out this time so, as I was bringing in a step ladder from the garden
late one afternoon, I thought, now is as good a time as any so I went
up the ladder and loosened the wire that secures the lid. Sure enough,
a healthy white maggot was waving about on the top of the box so I evicted
it then stretched up to look into the box. There’s always a bit
of apprehension opening a nest box in case you find dead chicks in it
but looking up at me was a very live Blue Tit, sitting on top of an
old nest. It didn’t seem alarmed and didn’t attempt to fly
away and I closed and secured the lid. Lucy had seen one flying out
one morning so evidently they’re using the box for a winterBack

Lucy had seen one flying out one morning so evidently they’re using the box for a winter night time roost. I wondered should I remove the nest material earlier on the following day but decided to leave it until later in the winter. I know I wouldn’t be too happy if I came home and found someone had thrown my bed away! One of my local wildlife highlights of the year was at the end of March when we saw a flock of Crossbills on top of Monterey Pines on Dalkey Hill. Although regular visitors to the hill, usually they’re notoriously difficult to see, often landing high on the conifers and blending in very well so getting a good view of a little flock of red males and green females, perched on the very top of a tree bathed in the rays of the rising sun was a real treat. |
Another
highlight of the year was when, coming out of the Lidl store car park
in Bray one gloomy night, Lucy spotted, flying along the adjoining avenue,
a Long-eared Owl. It was flitting along the street lights, perching
on top of them and scanning the ground underneath for prey. Our low
point on the hill was last year’s winter being the first we didn’t
see any red squirrels. It’s almost 18 months since we’ve
seen any in the park and, as far as I know, nobody else has seen any.
It was almost inevitable that once the grey squirrel reached Dalkey
and Killiney Hills in 2005 the reds would gradually die out but it’s
still a very sad loss. Providing flowers, plants and trees for pollinating
insects has became high on many agendas |

I was delighted I had left them alone. You would imagine a plant classified as a ‘noxious weed’, one that can result in farmers being fined for letting it grow on their land, due to its potential to fatally poison horses and farm animals that eat it, would be an undesirable addition anywhere. I knew the leaves of Ragwort was essential as a plant food for the larvae of Cinnabar moths but it was only this year I discovered its flowers are a brilliant food source for butterflies, bees, hoverflies and many other insects. It is actually listed as one of the top ten pollinating plants, attracting up to 200 species of invertebrates, and is one of the flowers most frequently visited by butterflies. |
