I have just been away for a week. No surprises there, and
Costa Rica was sensational. However when I came back look what I discovered is
now in my garden.
Persons unknown have dumped a huge unsightly pile of sticks
in the top of my beautiful Monkey Puzzle tree. What was a lovely candelabra
shape, a thing of precision and of daily happiness is now a complete mess. Whilst it is
tempting to blame the children or squirrels, the actual perpetrators are a pair
of industrious Magpies who are in the process of making an absolutely gigantic
nest. I have mixed feelings about this. On the one hand I am very pleased – I
will be able to watch a family of Magpies at close range – the new turret at
Chateau L is at exactly the right level to get a really good view of all of the
comings and goings. Magpies are characterful birds with bags of personality,
clever and inventive. More interesting you would say than a Blackbird.
On the
other hand my Monkey Puzzle tree is a source of great joy to me – it is, as
older readers will perhaps recollect, the main reason I live in Chateau L. I
doubt the nest will be detrimental to the health of the tree, but it just looks
terrible, and might get worse as the parents and (hopefully) chicks start
chucking waste out of the side of the nest. And then of course there is the
threat that Magpies as a species pose to smaller birds, several of which also
nest in my garden – Blue Tits, Robin, Goldcrest. The eggs and chicks of all of
these are excellent foodstuff for Magpies and are known to form part of their
diet, albeit that studies suggest that Magpies do not pose a conservation
problem to garden birds. I’m not sure what a “conservation problem” is in this
context, but I suspect that it means that a certain level of predation by
Magpies has no discernible impact on common species at a national level, but
that at a local level (as local, say, as my garden) there could be huge
variation. Personally I now have great concern for the other birds that I know
live and breed in the grounds of Chateau L, but it is what it is and nature will
run its course. My Blue Tits are in a nest box and should be OK, but the others
are not. Red in tooth and claw as they say. But why couldn’t they be
Oropendolas?
It is very distressing when predators move in. Here in Melbourne the Indian myna is pest. I used to have numerous silvereyes in my back garden (http://www.birdsinbackyards.net/species/Zosterops-lateralis) then the mynas moved in and now I have none. Not only do they drive other birds away, eat their chicks etc, they also kill each other! They are really horrible birds. Once a year the rosellas come and take all of the almost-ripe figs from my tree, but otherwise the only other birds are spotted doves.

ReplyDeleteAt least these are native, but still.
