We were watching this pair of Great Grebe for more than 20 minutes. She was at the floating islet, watching and arranging sticks. He was catching fish as shown in the last photos. It was long trying to swallow one. I thought he could not make it but in fact he did. A bit later it got near the islet and she began to stretch her neck waving it. A couple of minutes later she got off the islet and both swam. We did not see them come back to the islet while we were there. 12 6 16 © Photos and text by Claudia Mon

On Sunday 26th almost 30 Great Grebes were observed along the coast. As the tide was high some ventured near the reeds to catch fish and were lucky. It seemed there was plenty of fish to forage. The group was composed of juveniles and adults. Macá grande/Great Grebe2-10-2010 © Roberto Ares
On Saturday 2nd fewer individuals were observed. The tide was much lower, so they were farther from the coast
