Having to tackle high altitude, altitude sickness, tough weather conditions, exhaustion, and extreme cold are inevitable challenges you will have to face while ascending through the Himalayas. However, looking back, it was all worthwhile.

Heaven on earth.

Face to face with the Arctic's most prolific predator

Following the usual selfie routine, here's one taken by the shores of Hudson Bay on a very cold evening.

Sea ice is beginning to form along the shoreline as winter sets in. Soon, Hudson Bay will freeze over, and polar bears will start to roam on it in search of seals.

That moment when a huge boar gives you an intentional stare as it walks right past you, just meters away.

Finally, last night, after years of countless early morning patrols in the nature reserve, I managed to catch a glimpse of the king of the night: our very own resident Eagle Owl. Gibraltar Nature Rerseve Thinking Green GI

And so, it happened once again: this beauty has given me a truly memorable Christmas. It was definitely not falling off that branch. Thinking Green GI Gibraltar Nature Rerseve

Great day in the mountains surrounding Montejaque.

Amazing day today hiking up to Pico La Cocha with great company.

Can't Beat Nature

Grey seals spend most of the year at sea and may range widely in search of prey. There are only three populations of grey seals worldwide: one in the western Atlantic (northern North America), one in the Baltic, and one in the eastern Atlantic.

The Strait of Gibraltar never fails to impress. Today, we were fortunate enough to observe four sperm whales among a variety of other species.

Sperm whales are the largest toothed whales on the planet. They are exceptional deep divers, capable of holding their breath and diving hundreds of meters to feed on deep-sea squid and fish.

On last week's outing to the Straits of Gibraltar, we were treated to a rare sighting. A flock of approximately 20 Black Terns made an appearance, and they put on an incredible show as they delicately dipped the surface of the sea to catch small baitfish.

Another year and another MedSteps5Challenge done and dusted. A huge shout-out to Mark Cooper and the rest of the team from HM Prison for organizing this incredible event year after year, all in support of cancerreliefgib . 👏👏👏
