White ibis flock takeoff from roost in early morning - cypress hammock in Florida.

Ibis Moment -- Big Cypress National Preserve, Florida, U.S.A.

Fifth year in a row on different Capercaillie leks. This year started out slowly at 04.10 AM and about 5 males were displaying without much enthusiam until 07.30 when four females arrived. All of a sudden I had 15 males in front of the hide! Where did they come from. Wonderful recordings of the (almost) infrasound (32 Hz) when the males go "blind". If you listen carefully you will also hear mating of Pygmy Owl and hear when the Capercaillie males go quiet when a Goshawk calls in the distance.

Late autumn at the Adishi glacier.

Capturing the clean and quality sound of the glacier presents its unique challenges to overcome. One is the logistics and fitness of even reaching such a place, as they are mostly in high, remote mountains. Another is reaching the suitable area of the glacier, which is huge and presents a very demanding terrain that takes you time and energy to get to. Most easy access is at the front of it, the tounge where the ice ends, yet that is where the water comes running out of under the glacier. So in order to avoid the noise of the rushing water, I needed to reach a more upper stage of it, by following it along the edge. That presents another difficulty as the edges of a mountain are "eaten" by the glacier therefor they are completely crumbling and unstable with a high chance of collapse. You can hear stones falling down continuously. When finally reaching this narrow edge, I managed to come closer to the heart of this ice monster. This is where I was able to capture the ice avalanches and rock falls from much closer and farther away from the noise of the river. You can feel the vibrations and low rumble frequencies. Standing so close to it and witnessing its process is very different from anything else; it somehow feels like something extraterrestrial, something we are never used to witnessing in our lives. Yet it is a whole complex system by itself, existing there, doing its thing, basically just water.
