Wonder of the day

The Merveille du Jour is a striking species of moth, as the photograph of the individual above, that came this morning to the Banstead MV, attests. The direct translation of its French common name is 'wonder of the day' - most apt. The first one that I laid eyes on was at Spurn Bird Observatory in October 1985, when birding legend John Cudworth walked into the common room with one perched on the end of a finger. A 'wow' moment if ever there was one, as he was crowded by a mob of appreciative birders. For some it would have been the first time that they had ever taken notice of a moth. Here in Banstead they are not quite annual, so when one comes along they are rightly treated with reverence.

As we get to the back end of the autumn the number of moths, both individuals and species, drops off. But the lepidopterist cannot pack up the MV yet! It is a good time to jam in on a migrant or two, especially if a plume of warm air comes up from the south of Europe. There are also a number of new colonists that are on the wing now, species that I am more than keen to record here - Oak Rustic and Black-spotted Chestnut to name but two. And as we experience milder winters, there is never really a time when moths are NOT on the wing. It would take a big freeze and a couple of feet of snow to deter the most keen from switching on the trap.

One of the rarer migrants that I have recorded in Surrey arrived one late October, just under 30 years ago  - this Blair's Mocha. Apart from a single at Dungeness it is the only one that I have seen. But tonight the MV is staying indoors, as a strong SW and heavy rain is dictating events.

Goldfinches and Lavender

Image
We have three medium-sized Lavender bushes in our back garden. Throughout the summer the flowers (which last for several months) are a magnet for insects and give off a most restful aroma. As tempting as it is to cut the dead stems in the autumn, we always leave them, as we know that during the late winter we will get visitors to feed on the seed heads... This video was taken from the kitchen window this morning. We will normally see one or two birds over a few days, but have had up to 14 at once. We never tire of watching them. Lavender is a wonderful plant to have in the garden, with year round natural history benefits. So what are you waiting for? They are readily available at a garden centre close to you right now! There is an historic association with Lavender in this part of northern Surrey and south London. Lavender fields have been harvested for many years, with one particular field close to Woodmansterne being very popular with day trippers. A significant proportion o...

Welcome back!

In November 2005 I purchased a pair of Swarovski 10x42 EL binoculars from The London Camera Exchange shop in Guildford, for the then princely sum of £899. These bins have served me well, with almost daily use in all types of weather, testing their durability to the maximum - salt water spray, deluges of rain, 38C temperatures, dust, dirt, slight knocks... and apart from the armour coating that had started to bubble and come away from the body, nothing to be alarmed about. Then, in the summer of 2022, I noticed that I had a problem when close focusing - the outer focusing wheel would lose grip and it would take me an age to regain a middle-ground distance of focus - plus, over the next few weeks this outer focusing wheel became loose. I resorted to the use of tape to keep it all in place, but realised that I had to do something about it in the long run. For a while I did consider buying a new pair - after all, they were then 17-years old - but they were still optically superb. It seemed...

A special day

In birding, timing can mean the difference between an average day in the field and that of a spectacular one. Good timing can be helped by reading the weather conditions correctly, or understanding local conditions but it is more often down to pure luck. In this case, I just got lucky... I had not visited Dungeness since March 2022, quite a gap for me. It was high time that I once more trod the shingle and my timing of a visit was down to several factors, mostly a personal liking for mid-late autumn but also because I needed to be at home until September 20th and could not make the journey south until then. I also chose to stay at the bird observatory for a few days rather than make it a day trip. All this conveniently found me stepping outside the observatory's back door in the breaking dawn of Sunday 22nd September, quickly making my way to the fishing boats, an area I prefer to stand to best appreciate any visible bird migration, an aspect of birding that I find exhilarating.  A...
