When we had the new pond put in, way back in February, the frogs moved in almost straight away. There was a lot of croaking and and even some amphibious cuddling, but they completely failed to produce any spawn. I guess the pond was just too new and they didn’t feel it was up to scratch yet. The frogs may have let us down (I did try not to take it personally), but the newts, when they arrived, have more than made up for it.
The first newt plopped into the pond at the beginning of April and was quickly followed by many more. We never really knew how many we’d got, but I reckon at least a dozen must have found there way there in the end. Here’s the first ever one, popping up for air (the pond looks so bare looking back at it now, the plants have filled it out so much more since then).
They are all Smooth or Common Newts as far as we can tell, but they are still absolutely fascinating to watch. For the first few weeks in April, the newts we saw looked fairly laid back, with not much action; just occasionally popping up to the surface for a gulp of air. But as the breeding season progressed, we started to see courtship behaviour and could see the difference between the males and females.
The females are relatively plain coloured varying from beige to olive brown to dark grey. Their bellies in the breeding season go yellower with dark spots – you can just about see this in the female below.
The males tend to be much more jazzy. Certainly the ones in our pond were spotty all over, with a yellowy orange belly and a crest running down their backs and along their tails – visible below. (although the crest of the male smooth newt is quite marked, it is apparently nothing compared to that of the Great Crested Newt – clue’s in the name I suppose!)
Courtship consists of a lot of tail waving from the male – sometimes very energetically, almost aggressively in his determination to impress the ladies. Having got her attention, he deposits a packet of sperm, which she then manoeuvres over to fertilise her eggs. In the video below, you can just make out him producing a tiny white packet of sperm at about the 20 second mark.
There can be quite a lot of chasing each other around – sometimes more than just a pair; we’ve seen 4 or 5 chasing each other in a conga line across the pond.
The female lays the eggs individually on the leaves of aquatic plants. Water Forget-me-Nots are apparently a favourite for this, so we made sure there was plenty in the pond. The females grasp a leaf between their 2 back legs, folding them over and depositing an egg inside the fold. She then glues the leaf together and holds it until it sticks.
I particularly like this zen looking female laying eggs.
The females take so much time and care choosing the perfect spot for each individual egg. The next couple of videos show them carefully selecting and positioning each egg.
The eggs were small white blobs in a layer of jelly. Most of the time they were hidden in their protective leaf curls, but occasionally the leaves popped open to reveal one.
We first started seeing baby newts swimming around the pond in mid-May. These first ones were tiny, less than a centimetre long and with no legs.
By early June mini newts with tiny legs had developed. The legs were virtually transparent still, but fully functioning.
They gradually grew, the legs thickening and strengthening, but still retaining their gills.
To get clear shots of the baby newts swimming/walking I very carefully caught a few and filmed them in a tank, before gently releasing them back into the pond.
The tank videos are good for seeing the detail, but it is so much nicer to get them swimming free in the pond (although considerably trickier to film). I love this little one determinedly hunting tiny water fleas as he paddles around.
I’ve not managed to find any young newts who have fully metamorphosed into efts and lost their gills yet. I’m sure some of them must have done by now, but they have probably left the pond and dispersed into our plentiful weeds. There is plenty of cover around the pond for them to hide in. The closest I’ve got is this one resting on the frogbit (should that be newtbit?), but he still has gills.
A lot of the young newts or efts of course won’t make it to adulthood. Lots of things will eat baby newts, not least of which is this Great Diving Beetle which landed unceremoniously in the hedgehog’s water bowl the other night and may have then moved on into the pond.
The efts won’t mature into adults until they are 2 or 3 years old, so it will probably be a couple of years before these youngsters return to the pond to breed. But hopefully some at least will make it and the pond will have done its bit to increase the newt population in our garden. Watching the newts court, lay eggs and develop into efts, has given us such pleasure during the sometimes bleak year that has been 2020; the least we can do is repay them by providing a suitable weed-filled garden for them to live in. They don’t mind that we’re too lazy to weed.

We had a pond this year so hoping the newts will discover it!

I’m sure they will – it’s amazing how quickly things move in.
