Mosquera Island
From a distance, Mosquera looks like large sandbar rising out of the water. It appears as if the Island, which is small, is a beach of bright white sand. Getting closer, we could see that there was also some black volcanic rock. But the island is very flat and mostly beach. From the boat, I could see Sea Lions on the sand, as well as some bright red things on the rocks (which turned out to be Sally Lightfoot crabs.
At 3:30 PM, we landed on Mosquera Island. There were many, many sea lions on the island. The dominant bull immediately began to bark and assert his authority, showing us who was boss. While most sea lions are friendly and relaxed, we have been advised to stay clear of the dominant bulls. If he thinks you are challenging him, he may just attack. After a few minutes, this bull sea lion calmed done, apart from occasional outbursts of barking.
Every few steps along the beach were sea lions, mostly female sea lions (the "harem") and young sea lions of various ages. The baby seal lions were the most playful, as you might expect. The sea lions are not scared of people whatsoever. Sometimes they react if you get too close, but "too close" is usually measure in inches and not feet.
We also saw our first marine iguanas and sally lightfoot crabs, and a single striated heron.
