Hi Bertie.

Buying a bat detector: there are many to chose from.

There is a terrific one for an i-pad. [I don't have it!] Look and drool!

Best starting point is your local bat group. Go to a Bat Watch and see what they get up to.

Re the relationship between fruit/food availability and insect numbers: I will offer you a possible suggestion to research. Larval wasps are carnivorous and are fed on insects/larvae by the workers. Adult worker wasps on the other hand are attracted to carbohydrates - like nectar, honeydew, stolen honey and that jam pot or can of coke - and of course ripe and rotting fruit. At the end of a summer, a good insect year [food for larvae] will also have a good adult wasp population. A bad insect year is often also a bad fruit year due to poor pollination and/or bad weather. There will therefore be fewer adult wasps chasing after less fruit. So there is a relationship, but it is functional and real, a consequence rather than intuition.  Make sense? Here's some general stuff on Wasps:

Same observation here, I suppose only 30-40 miles away. Anyone, say, in East Anglia who could comment?

This observation is not necessarily related to the size of wasp population so much as the timing of maturation of the last hatch and the related spreading out of workers in search of carbohydrates to feed on. They no longer have larvae to feed, they soon will die, meanwhile they want to eat. The significant question is how many queens have been produced, getting ready to hibernate. That will have an effect on next year's start-up population.

We've also heard the owls, there's at least two in the area, and watched the bats flying at night, after the easy smorgasbord available, of flying insects attracted by the outside lamps. It's great here. There's also some deer living in their woodland but we've been too noisy for them to show themselves  to us just yet, but we have heard them and seen the signs that they are about. The family cat has been keeping the small rodents away from the house the last two days as well, but leaving them outside our Gite! At least she's doing her job I guess.

Keep an eye out for Pied Flycatchers, Caz. They are on the move. I've had about 36 reports today along the Lincs coast.

I've just looked it up.  It was once a common breeding bird across the UK, which is something I didn't know. Someone from the C17th would often see one, now they are an rare passage migrant. Lets keep our fingers crossed we don't lose more common migratory birds - though I think of the wood warbler and nightingale...

The same cat killed an adult blackbird two years ago (the scream it made as it died remains with me), and it's nabbed one of the pigeons too - my neighbour's dog dove into a bush and pulled out the remains.

Infuriating, frankly, not only do cats leave piles of parasite-ridden poo for you to tread in, they infect between a third and a quarter of the UK population with a brain parasite (which modifies behaviour in other animals to make them less fearful of cats). They then kill the birds in my garden, something replicated across the country.

Poxy things. The sooner we follow Australia's laws and require them to be kept indoors, or in a "catio", the better. "Oh, but they need to be outside", the cat-lovers say... (or, in other words, our pets are your problem). Well, by that token, dogs would love to roam in packs and kill or injure small animals, like cats, but we don't let them. It's the price paid for domestication of an animal, they lose their wild liberty but gain comfy accommodation and veterinary care in exchange.

Since then it’s rained and rained, on two days almost all day. ‘How are they managing to feed their chicks? To catch insects in this lot’ I wondered.

This evening I’ve had time to do a bit of checking and watching. I couldn't see any chicks in the nests. I’ve seen no house martin or swallows all day. But at sunset…I saw three, then four all gently sailing on the breeze, quite high up (‘that’ll be the adults at least’, I thought, ‘but where are the chicks?’). I waited, several minutes passed, then a saw eight, ten, and a swallow! (I though they had gone), then more, so many I couldn’t count them (above twenty it get very difficult, it become educated guesswork). Then more swallows, maybe our three pairs, hard to tell at the speed they move. Then, they sky goes empty again.

It gets darker, more, many more, than twenty appear again (perhaps as many as 30?), swirling lower but at speed, and then the irritated noise only a hirundine wanting to go in a nest can make.

I left them to it thinking how blessed we are to have such fantastic, almost symbiotic, birds share our home and how lucky we are to care for them..and how amazing it is they’ve manages to fledge chicks in the recent weather! At the moment it is ‘fare well my friends’ soon it will be ‘farewell my friends and I hope to see you next year’ Bravo to all of them!

I learnt that there are more than just seagulls (dry humour alert) and we spotted these other species on the list link. Lots of LBJ's.

I know a few of the others but my knowledge is at basic level.

No white tailed sea eagles this time, though these tend to turn up in the winter in this Bay.

Our lemon tree was distressed by the recent lower temps - she had been looking splendid earlier. Maybe time to wrap her up for winter?

Thinking of insects - we have only seen single worker wasps and honeybees this year in a garden usually teeming with insects. A Red Admiral and 2 Small Tortoiseshells yesterday - the Torts checking our windows with a view to hibernation. A recent visit to one of our favourite limewoods was almost fungus-free'. Just a couple of "little brown nasties". The forest floor was very dry indeed. No hedgehogs on camera last night.

Dates when I've recorded ivy first coming into flower in this area: 24/9/08, 9/9/09, 15/9/11, 19/9/12, 7/9/14, 20/9/15, 15/9/16, 20/9/17 , 29/8/18, not recorded 2019/2020, 3/10/22, 6/9/23, 14/9/24. Not systematic, but I normally get out for a longish country walk once a week.

3 Hawker spp dragonflies were hunting over the garden this afternoon, plus 2 small tortoiseshells and several "whites" going about their business. Perhaps 3 honeybees foraging and several unidentified flies! A thirsty grey squirrel at the birdbath for a long drink.

I don't ever remember ever seeing so many rowan berries as this year. The trees are weighted down by them, lending places where there is a lot of rowan a reddish hue from a distance.

I wonder if it's a Dartmoor thing? Or more widespread?

The same here too in this part of Dorset. The sedums are full of feeding bumblebees more than I've seen in one place (20 plus on a couple of plants) and honey bees too. What a contrast to earlier in the year. Butterflies a good range of species flying and feeding in the garden.

Swallows and other hirundines seem to have a had a good year here as well and getting ready for their migration south.

I find it hard to comprehend that anyone eats farmed salmon, given the harm they do to the environment and the risks to the stocks of natural salmon and sea trout. I also wonder how much the Scottish Government gets from the industry to allow these destructive practices to continue year in year out.

It's a big current issue here, Nick. Ironically, in Grimsby! 😬

Bit damp here today!!!!!!

"You may have bought a drink recently and noticed something odd: the once removable cap is now tethered to the bottle by a small strip of plastic. ...An EU directive was enacted in July, requiring that all single-use bottles have caps that remain attached."

"In the UK, 2023 beach surveys listed bottle lids as the third most common type of litter, while on the Dutch North Sea coastline, surveys recorded up to 128 bottle caps for each kilometre of beach in 2016."

Saying that, a couple of years ago, it was reported that a pair of swallows over wintered in Jersey.

To my great surprise this morning, before 9 am, I saw a large flock (and it looked like a flock) of hirundines (20+) crusing north over the house. Mostly young birds by the looks of it, and they looked slightly bigger than normal (but definitely hirundines not thrushes). 

A very surprising sight to see up here so late in the year.

Doh, I just noticed this! Swifts too!!??

Bloody Norah! Our swifts are long gone. The place seems knee deep in Yellow-browed Warblers!
