Twitching and wriggling in the pond

It's been three weeks since we told you about our first toads in the biotope – in the meantime, their offspring has hatched and is now shaking up the whole pond. We discover little tadpoles everywhere, eagerly foraging for plant remains and algae. As soon as they get bigger, small carrion will also end up on the menu.

Offspring at the pond

After ducks, newts, flatworms, and dragonflies, we have now spotted common toads (Bufo bufo) in and around our pond. They are by far the most widespread toad species in Europe. Usually they spawn already in the middle of March. This year, however, they had to wait a little longer due to the dry weather. It was not until the rainy days of April that a flock of toads set out for suitable breeding waters. A few of them tried their luck in our new pond. After spawning, the adult toads exit the water and leave behind meter long, densely packed egg strings. Depending on the water temperature, tadpoles develop after a few days. After two to three months, they have grown into young toads that head out into the big, wide world.

We keep our fingers crossed that our first tadpoles in the BioDiversum will develop well. However, our young pond still lacks hiding places as its aquatic plants are still growing. It will thus not be easy for the toad offspring, but not impossible either.

MPI-NAT… NAT… NAT…

Twice they visited us, twice we unintentionally scared them away with our enthusiasm (and our cameras): A pair of ducks has discovered the pond in our biotope! The pond still lacks food and vegetation to keep them on the Fassberg for longer. We hope that in the next few years it will be transformed into a habitat for ducks – and other water loving animals of course–, so that they do not only drop by for a flying visit!

All! These! Nests!

... are the result of cleaning our nesting boxes in the last weeks. 41, that is the yield of one year after setting up almost 100 boxes. From our observations, we even know that some bird couples bred twice in their nests. Most of the nests were most likely built by great tits, blue tits, and a few nuthatches.

By the way – for these two reasons you should clean your nest boxes either in late summer or toward the end of winter:

1) Birds don’t dispose of old, abandoned nests. Instead, the next inhabitants simply build their new nest on top of the old one. As a result, the next brood is always closer to the entrance hole, making the hunt easier for predators.

2) In addition to dirt, there are always parasites and pathogens in the nest boxes, which can endanger the brood in the coming year.

For 2022, we expect a greater run on our nesting boxes. That is because last year we were late in hanging some of the boxes. Now, however, the birds had plenty of time to familiarize themselves with the housing market. We are particularly curious to see whether our tree creeper boxes will be accepted. They have only been hanging since late summer.

Pond construction in fast forward 

Building the centerpiece of our biotope was a major undertaking. From March to October 2021, the diligent construction workers were plowing, digging, dredging, and planting. We filmed all the hard work and don't want to deprive you of the 2-minute video of our pond’s creation. Next to the construction site were our alpacas: Aren't they cute, how they munch their way over the meadow in fast motion?

If you want to see more details, you can find them in the long version of the video. Go on a discovery tour and see what it reveals!
- When can you see our alpacas and what weather conditions do they prefer?
- At what time is the water let into the pond?
- When is the opening ceremony taking place? 

You can find the answers to these questions here:

All-round view at the bird feeder

We recently set up a 360° camera at our year-round bird feeder. We wanted to figure out which guests we were actually hosting. And lo and behold, we actually had a VIP for a visit: A Grey-faced woodpecker (Picus canus) eagerly helped itself to the buffet. We are particularly pleased about this, because the species is considered endangered in Germany. Grey-faced woodpeckers are easily confused with green woodpeckers, which are much more common here.

In the video, our guest of honor bumps into a visitor we hadn't planned on. Take a look:
