My monthly BTO WeBS count along the Union Canal, Linlithgow to Philpstoun.
Wednesday 28th August 2013.
Start time 7.50am
End time 11am
Overcast, cool light breeze, a few patches of sun, no rain.
My first time doing this count since June, having been unable to make it last month.
What flood-field?:
Flood-field is sadly now absolutely not a flood-field, just a field. Hopefully the autumn rains will change that. So no water birds on flood-field today, rather, two pied wagtails, two woodpigeons, a few starlings, a few jackdaws and lots and lots of rooks. Somewhere far off a curlew was calling.
The signs of the change of the seasons are starting to appear but it's been a very productive summer: large groups of young house sparrows flitted along the tall towpath vegetation in front of me, sometimes a few tree sparrows foraged amongst them; often young goldfinches were alongside their parents, striking with their bright yellow wing stripes but lacking the beautiful red facial masks of an adult; all the starlings now have cream/white spotted metallic dark green chests but heads are still the dusking brown of this year's young.
At one point a probable sparrowhawk, mobbed by martins. My sighting was too brief to be certain but it flew low sticking mostly to vegetation, much less obvious than a buzzard.
There were water birds using the canal, but nothing of great note.

Gall wasps are minute parasitic creatures, this particular one about 4mm long. They lay their eggs on the host plant and, when the larvae hatch and begin to eat, something that I don't really understand causes the plant to morph and grow these incredible structures. There are many different galls in the UK, on many different plants. One that people are quite familiar with is the wood-like sphere the size of a large marbles, sometimes found growing on oak trees. Inside galls are chambers which the larvae live in until ready to emerge as adult wasps and begin the cycle again.

If you've time to spare, have a look at both.
