Camera Trap Quickies

When I visit Cannon Rocks I like to bring one or two camera traps with me. While the SecaCam was busy at the birdbath (see older post over here), the Bushnell NatureView HD was used for a day or two at three different locations.

We are fortunate to have some lovely Aloes growing next to our house. I don't understand how its possible but these Aloes are almost always in bloom throughout the year. If there is ever a time without blooming flowers then you will be sure to find at least one plant with new flowers already on the way. As a result these plants are a magnet for nectar feeding birds.

I've personally seen five species of Sunbird visiting these plants, not to mention all the other birds with a sweet tooth.

I had some Butternut pumpkin one evening for dinner and thought it might be interesting to see what animals might be interested in the scraps. I must admit I was quite surprised with the results.

Southern Boubou (Suidelike Waterfiskaal - Laniarius ferrugineus) searching for pumpkin seeds

The Southern Boubou was on the case immediately, and would come back time and again until there was nothing left. Interestingly it was the female that was the most frequent and persistent visitor.

The female was after the pumpkin seeds and didn't show any interest in the pumpkin peel or flesh. According to the internet pumpkin seeds are very nutritious.

What makes this interesting to me is the fact that these birds eat predominantly insect, snails, worms, etc. and small animals such as lizards and even baby mice. But they do also have some omnivorous tendencies, enjoying a drink of nectar and are keen to dig into some fruit, and apparently now we also know that the females enjoy pumpkin seeds.

I'm assuming that the seeds help to get the female in good shape for breeding (egg laying in particular)?

I've always wanted to try camera trapping on the sea shore, but my biggest concern has always been the fact that it is hard to hide the camera trap from people walking on the beach. I'm particularly concerned about poachers...

However, this time around I decided to take a risk and set out the camera trap for two night, in the middle of the week.

Because I only wanted to leave the camera trap there for a short time I decided to empty a can of tuna in front of the camera as some bait.

The Marsh Mongoose showed up on the first night. On the second night a Large-Spotted Genet made sure to cleanup any bits of tuna the mongoose might have missed.

I often find tracks of these two nightly beach visitors along the vegetation edge, but its good to finally see them "in person" doing their rounds up and down the beach.

Getting Fishy On The Rocks

My dogs, Scout and Mushu, enjoying the low tide

The Sony Xperia Go was my first smartphone, in fact it was the first cellphone I ever bought for myself. I really liked the fact that it was small, had a good camera and was water resitant. About a year ago I upgraded to the Sony Xperia E3 Compact, leaving the Go gathering dust. During my recent vacation at Cannon Rocks in the Eastern Cape I decided to see how far I could push the "water resistant" feature of the Go.

Definitely not National Geographic or BBC footage, but I'm fairly happy with the results.

Look carefully around the 2:15 minute mark, the one larger fish, I believe a Klipfish, catches one of the small ones. It happens so fast!

I'm going to guess this was the Super Klipfish (Clinus superciliosus), but I'm likely to be wrong since there are about 40 species found along the South African coast and my field guide only shows 8...

I was surprised to learn that Klipfish are internally fertilized and give birth to fully developed young.

I didn't only rely on the cellphone, but also took some photos the conventional way: With my digital camera millimeters above the surface of the water.

For some photos I couldn't get close enough to the fish, so I had to use the zoom to get close.

The tidal pools also contain "normal fish" like this unknown yellow finned character

I prefer using a "compact super zoom" camera, like my Nikon S9900. Sure the image quality isn't comparable with that of a DSLR, but it is a one-size-fits-all solution. The camera is small enough to carrying around with me wherever I go and it can instantly go from photographing a flower up-close to snapping a shot of a bird that landed on a rock in the distance. What I liked about this particular camera was the size and the fact that it has a built in GPS, making it much easier to get the GPS co-ordinates when I add the photo to WildLog. The WiFi features are also nifty.

Trying to identify these fish is a daunting task... I'm using the excellent Two Oceans field guide, but I suspect some of these tidal pool fish are juveniles of larger species... The field guide also definitely doesn't cover all species either, but only lists a few common / unique ones.

I have no idea what type of fish this little beauty is, never mind the actual species...

Next time you are at a beach with tidal rock pools consider doing yourself a favor by spending an hour or two at low tide discovering the variety of life.

Pssst, I'll tell you the secret: Don't give up after the first 5 minutes ;)
