Jellyfish, Shrimps, Catfish and Crabs

Last week I went to the beach with my family. Me and my cousin, Amelia, had a walk by the sea and found a lot of jellyfish. They were all different sizes but we didn't know what type they were. We didn't touch them as we knew they sting. When I got home I looked on the Wildlife trusts website and found a good picture at the bottom.

Compass jellyfish

This type of jellyfish will eat small fish, crabs and even other jellyfish. They give a very nasty sting so luckily we didn't touch them. Once they have stung something, jellyfish often leave the tentacle behind and can still sting with it even when it is not connected to their body. Young fish can often be seen swimming around the compass jellyfish's tentacles, giving them protection from predators. People are still not sure why they don't get stung and eaten by the jellyfish though!

After we had a look at the jellyfish and put them back in the sea with our spades, we went rock pooling. We caught 2 crabs, 5 shrimps and 4 catfish. We kept them in a bucket for a little while and then let them go.

    So cute and squishy! But no, I wouldn’t want to test that 😝
    I read about a rather sad turn of events in the fish-jellyfish relationship. When the seas grow more acidic with extra carbon dioxide (because of pollution), the little fish tend to leave the jellyfish and are at risk of getting eaten more.

Waxwings

Image
Recently there have been waxwings in our local Aldi car park and I wanted to see them for myself to get a good photo. Waxwings are birds that winter in this country and travel here from Scandinavia. According to the Wildlife Trust, sometimes only 100 or so Waxwings come to the UK, but other years they come in their thousands and this is known as an irruption. I would would say this year must be an irruption year as they seem to have be spotted all over the country. Rowan berries are their favourite food, so supermarket car parks are always a good place to spot them (Not were I usually go to do my birdwatching!). These are the first ever Waxwings I have seen and it was an unforgettable experience. We arrived at the Aldi car park at about 8am (ish), just as we arrived, we saw someone driving off and thought maybe we were just out of luck and the Waxwings had moved on. At first we didn't see anything except a bush with quite a few berries, but a few moments later a flock of about 20 b

Spurn Bird Observatory Migfest 2023

 Last weekend we went to Spurn to attend Migfest for the 2nd year in a row. I was full of excitement and couldn't wait to see what we could find! It was a long 4 hour drive from school to Welwick but it was worth it. The air bnb was nice and had a hot tub, which was a bonus!  One of the things we did was go on a Unimog trip to The Point at Spurn. That trip held loads of amazing species like Merlins, Reed Bunting and Pied Wagtails. Also we briefly saw a Roe Deer! On the Sunday morning, I attended 2 Young Birder Activities, which were bird ringing and a youth walk. At the bird ringing, we got lucky! We ringed a Pied Flycatcher (my first ever one to see!), Goldcrest, Blackcap, Willow Warbler and Meadow Pipit. What a lovely variety! On the walk we were lucky enough to see a lot of nice species, including Water Rail, Golden Plover, Spoonbill, Little Grebe and Marsh Harrier. It was nice to go for a walk with other keen young birders. I also got a Rare Bird Alert account for free as I was

BTO Bird Camp Wales 2023 Part 1

 Recently I attended the 2023 BTO Bird Camp for Wales for the 2nd year in a row. A lot of the friends I met last year like Deri, Tyler, Gabe, Finn and more were there but there were also some new faces. We arrived at the same bunkhouse as last year and waited for everyone to arrive. After that we set up our rooms. I was sharing with Deri, Tyler and Finn. After setting up we headed to the yard and played a game to learn each others names. We had to throw a ball to someone and say their name. I think I was better at throwing than remembering everyone's names! For dinner we had a very nice chilli made by the BTO volunteers with guacamole and nachos. We then set some camp rules that everyone agreed on and signed it. That stayed on the wall for the rest of bird camp. Next up was the evening activity, Bat walk. Bob and Annie, the experts who were there last year did it with us and also another man (I told you I'm hopeless at names!), who was a bat expert, came along just for this act
