Galapagos Day 6

Up early for a walk around North Seymour Island. Saw male frigatebirds trying to attract females by inflating a large balloon sack on their throat. Also some some humpback whales from a distance.Back to the boat for breakfast, then we boated to Baltra to drop off passengers and pick up new passengers.I gave Glenn and Sarah (Aussie couple) some postcards to mail for me, then just as they were leaving the boat, I remembered that I didn't write addresses on them. Doh! I got them back before they left.We went to Baltra beach while new passengers boarded. Tried snorkelling, but very murky, not much to see.Had a few hours to kill before going to Bachas Beach for a hike to see pink flamingos (only three this time of year) and a great heron. Then hung out on a beautiful beach for snorkelling and swimming. At one point, a massive flock of birds all took off from behind a rocky outcrop and flew overhead, thousands of them, heading to the far end of the beach, where they appeared to be gorging on something in the ocean. Consuela (Italian girl) was walking down the beach, and tsome pelicans came in very low over her and she had to duck to get out of the way of them. It was hilarious. I happened to take a great picture just as this happened. Also saw Sally Lightfoot crabs.After the hike, we had an unexpected briefing back at the boat. Gustavo, our guide, was leaving, and we were getting a new guide. Over the past couple of days, he had gotten in trouble from other guides for letting us wander off trails and such. Gustavo even took us off the path at one point to see an iguana. We suspect other guides reported him, and he was being called back for reprimand and re-training. Or maybe losing his job.We had a briefing with the new guide at 6:30pm, then we had a toast with the crew. They were all dressed up in their mariner uniforms, such a change from the dirty t-shirts and jeans we've seen them in up until now.In the evening, after dar, watched fur seals and pelicans fish using the help of the lights on the boat. The sea lion would start chasing a fish, the fish would jump out of the water and 'fly' along the water, trying to get away. Sometimes they'd slam right into the side of the wooden dinghy....BONK. BTW, Google Sky Map is amazing, I'm glad I brought my phone.
