Toby: Hi, I’m Toby. I want to tell you about an amazing evening excursion I went on last week. We took a small vessel down our town’s river to go bat-watching! I went with my parents, but the whole thing was actually organized by my uncle. He used to be a biology teacher, which was his first career, but now he works as a wildlife photographer, so he knows all the absolute best spots for nature watching in our local area.

When we got down to the riverbank just before sunset, I saw our vessel waiting for us. I was honestly expecting a typical noisy tourist cruiser, or perhaps maybe just a simple rowing boat given how narrow the river is. However, this vessel was actually equipped with an electric motor, which made it completely silent as it moved through the water. The captain explained that this meant we wouldn’t scare the shy animals away as we approached.

Once we set off and the sky began to darken, our guide started sharing some truly fascinating facts. I had always thought bats just had incredible eyesight to see in the pitch black of the night. Actually, they rely entirely on sound waves to find their way around, constantly bouncing echoes off trees and bugs to navigate effectively. It’s a biological system called echolocation, and it’s highly accurate.

Speaking of bugs, I naturally assumed that all bats strictly survived on a diet of moths, beetles and mosquitoes. The guide told us that while that’s absolutely true for the many species we have right here, in other tropical parts of the world, a large number of them actually prefer fruit, and some even swoop down to catch fish! That really surprised me, as I had no idea their diets could be so varied.

Because humans can’t naturally hear the extremely high-pitched calls of the bats, we needed some advanced technology to help us tune in to their frequency. I thought we’d just use a standard bat detector like I’ve seen researchers use on TV documentaries, but the guide actually gave each of us a special microphone connected directly to a comfortable headset. It felt very professional.

When we first put the headsets on and switched them on, I wasn’t entirely sure what to expect. My mum said the chaotic noise sounded a bit like a weird orchestra tuning up before a concert. To me, though, it didn’t sound like music at all; it was exactly like a ticking clock that kept getting faster and faster as the bats got closer to their prey. It was thrilling to listen to.

Even though we went out in the middle of summer, the temperature dropped significantly once the sun went down and the mist rolled in. The tour company had kindly provided some thick blankets for everyone, which was nice, but I was extremely relieved that I’d decided to pack my winter coat, because the chilly breeze coming off the water was absolutely freezing.

For the first hour of the trip, we only saw one or two lone bats circling near some old willow trees. We then floated silently past a wide grassy meadow, but it was still remarkably quiet. However, as we approached a massive stone bridge that crossed the river, dozens of bats suddenly emerged from the deep cracks in the masonry. It was an incredible spectacle to watch them swarming above us!

We didn’t just see bats on our journey, either. At one point, my dad pointed out what he firmly thought was a small duck swimming alongside us in the gloom. But looking closely through my camera lens, I realised it was actually a water vole. I managed to get a brilliant, clear shot of it just before it vanished into the tall reeds.

The whole excursion was so inspiring and educational. I was originally going to write a standard article for the school newspaper about my summer holidays. Instead, I’ve firmly decided to create a biology project focusing exclusively on protecting our local bat species and their habitats. I honestly can’t wait to get started on the research!

Chloe: Hi everyone, my name is Chloe, and I’m here today to tell you about an incredible wildlife-watching boat trip I went on just last week. I am currently studying ecology at university, so I usually organise these types of coastal excursions purely for my coursework and field research. However, this specific trip was completely different because it was actually a birthday present from my parents. They knew I desperately wanted to see some marine life up close, but in a sustainable way.

When we arrived at the bustling dock early in the morning, I got my first look at the vessel. Given the size of the estuary we were exploring, I’d naturally assumed we would be travelling on a standard diesel cruiser, or perhaps even a large sailing boat. But to my absolute surprise, the boat was equipped with a state-of-the-art electric motor. The captain proudly explained that this meant the vessel could glide through the water in almost complete silence, without any of the rumbling vibrations you usually get.

Before we departed, the captain gave us a comprehensive safety briefing and explained exactly why this silent running was so critical. You might logically think it’s simply to stop the shy animals from swimming away before we can photograph them. But environmental research shows that loud engine noises can drastically increase the stress levels of the local marine life, affecting their long-term health and breeding patterns.

Once we set off, we slowly made our way into the vast estuary. I genuinely thought we’d head straight out into the deep ocean channels to find the larger animals. However, the captain carefully steered us towards the shallow waters near the salt marshes instead. He explained that these sheltered areas act as a vital nursery for marine life, and that’s where the most activity happens during the incoming tide.

I had my camera ready, desperately hoping to see a pod of playful dolphins, which this particular stretch of coastline is moderately famous for. We didn’t spot any of those on this occasion, unfortunately, but we were treated to an amazing, unobstructed view of several grey seals basking on a nearby sandbank. It was an absolute privilege to see them so peaceful and undisturbed.

Because the boat was so incredibly quiet, we were able to drift surprisingly close to them without causing any alarm. The guide told us to watch their movements carefully. I fully expected him to tell us about their sleeping habits or migration routes, but instead, he gave us a fascinating explanation of their unique hunting technique in the murky waters of the estuary, and how they use their whiskers to detect moving fish.

Even though the sun was shining brightly when we initially left the harbour, the wind quickly picked up across the open water and it got surprisingly chilly. I had packed a thick woollen jumper in my bag just in case, but I was extremely grateful when the crew handed each of us a thick thermal jacket to wear over our clothes. It really kept the freezing sea breeze out.

As we drifted back along the coastline, we were looking out for native seabirds diving for fish. Unfortunately, not everything we saw was a beautiful part of nature. You often hear terrible stories on the news about huge fishing nets causing major problems for marine wildlife. But what we spotted bobbing along near the reeds was a discarded plastic bottle. It was really depressing to see everyday litter making its way into such a pristine environment.

Towards the very end of the trip, I leaned quite far over the wooden railing to get a better look at a magnificent heron standing in the shallows. I managed to keep a tight grip on my expensive camera, which was a relief, but my sunglasses slipped right off the top of my head and vanished into the dark water below! It was entirely my own fault for not taking them off and putting them in my pocket.

Despite losing my belongings, the entire boat trip was totally inspiring and deeply educational. I was originally going to write a short article for the student magazine about eco-tourism. However, the experience has motivated me to do something much more practical, and I now plan to spend my summer volunteering for a local conservation charity to help actively protect these amazing coastal habitats. I can’t wait to get started!
