Swooping Swallows – September 17th

At first light Barn swallows swooped around out the front window but disappeared by afternoon. Bate balls of herring have become more and more prevalent in and around the reserve creating great gull frenzies and bring more whales in and around the reserve. Orca cruise by every few days and Humpbacks are spotted every day it seems. I’ve been busy working on painting restoration projects before the rainy season, scrapping, priming and painting metal doors around the reserve. Now that its cooled the thorny invasive plants have dried and I’ve began the process of pulling them. Fleas brought here upon the sea lions infest the thorns and its necessary to tuck pants into socks, wear big rubber boots and try to keep gloves tightly sealed in cuff of jacket. The sea lions at the Jetty have become more and more and push through the electric fence a few times a day. I have slowly been working my way around the fence stacking rocks upon the bases of the posts which has been helping with the damages and constant knocking over.

With more and more sea lions arriving the electric fence repairs are becoming more frequent and more damaging. Each morning on average at least 2 sections are broken. Often many blocks/ posts are knocked over and simply need to be stood back up and repositioned. Topped up the batteries with our diesel generator this morning while wandering the reserve to observe and do our weekly animal census.
