Return of The Terns
North of the beach goers, was a long lagoon formed by recent, very high tides. Three Terns were standing in shallow water, two were bathing. The smaller Elegant Tern was flanked by two larger Royals. In the photo you will notice the smaller Elegant (right) has a slightly drooping, slimmer bill while the bill of the larger Royal is more robust in size and color. Trying to identify the two species in a large flock may require patience.
Arriving at the same time as the Terns are the Heermann’s Gulls. Terns dive for fish, Heermann's Gulls do not, instead they steal fish from the Terns. Technically speaking, Heermann’s Gulls are kleptoparasites, they feed by taking prey from another animal. Heermann’s Gull is often found in close proximity to a flock of Terns.
Nearly forgot to mention that on the Torro Creek beach, also know as Dog Beach, there was a mixed flock of Long-billed Curlew and Whimbrel. Since the dogs were playing down by the water, I was able to spend time looking at the flock, in particular two smaller resting birds. Could they be juvenile Long-billed Curlew? I had never seen one. They stood up. Yes! They were juvenile Long-billed Curlew. That first time sighting definitely made my day.
