Summer approaches: days grow warmer, sunbathers arrive, surfers blanket the waves, birds begin to leave. Still we found a record-high (for May) species count, while total birds was below average. Nesting season is well along: Killdeer chicks have been spotted, hummingbirds sat on nests, Red-winged Blackbirds

displayed their epaulets, Black Phoebes collected flies, and Mockingbirds and Song Sparrows sang from nearly every bush.

Present since November, the Osprey apparently has been able to find sufficient large fish to stay satisfied. Many of us saw one (or more, as the location kept changing) such fish jumping high out of the water, and someone wise to the ways of fish identified it as a Steelhead (trout), a species endangered and long absent from the lagoon. I recall several meetings of the lagoon

task force, decades ago, at which a representative of Trout Unlimited spoke of the steelhead and his organization’s hope that the lagoon and creek could again be a home for them. It didn’t seem likely to me at the time, but now…things are looking up! The steelhead’s presence in the lagoon, first noted on 5/15/14 by fish monitors, was soon reported elsewhere (KPCC, Malibu Patch, KCET). The local anti-lagoon-reconfiguration diehards immediately scoffed, of course. Personally, I’ve often seen Mullet – another large fish – in the lagoon, but can’t recall ever seeing one jump. I have seen several species of trout elsewhere (Oregon, Michigan, Great Lakes) and they are definitely jumpers, exciting to watch. While we’re on the topic of fish, the Tidewater Gobies are reportedly doing very well indeed, as their habitat was greatly increased by the lagoon channel reconfiguration.

[Comment inserted 6/6/14
According to an article in the Malibu Patch, “An adult steelhead trout, approximately 20 inches in length, was discovered on May 15 during post-construction fish monitoring by the Resource Conservation District-Santa Monica Mountains, California State Parks and The Bay Foundation.”  ON 6/6/14 I received an email from Mark Abramson: “The jumpers are almost always striped mullet. However Rosi and her fish team saw a 20-inch steelhead in the back of the channel when they were there doing fish surveys.”

So it seems that the fish we saw jumping on May 25 were actually Striped Mullet, and not the steelhead. Link to slide show of jumping Striped Mullet on EcoMalibu. Malibu Patch has a picture of the steelhead.  End of inserted comment]

Also reported from the lagoon were numbers of dead Brown Pelicans (we saw three) as well as unusual numbers of adult pelicans. They should be nesting on offshore islands – Anacapa, for example – rather than lounging at Malibu Lagoon. It turns out that Brown Pelican nesting failures have been reported throughout California and Baja. One Baja colony, which would normally have over 10,000 nestlings by now, has produced well under 100. Failure of the nests is due to the lack of suitable prey fish, which in turn is the result of a change in ocean currents, which is believed to be linked to the ENSO (El Nino – Southern Oscillation) phenomenon. This, in addition to other factors, is leading scientists to predict El Nino for next winter. Stay tuned!

Birds new for the season were: White-tailed Kite, a single Bonaparte’s Gull, a very *uncommon and unexpected Common Tern, Mourning Dove (which are always close by, I don’t know where they’ve been hiding), Western Wood-Pewee, Pacific-slope Flycatcher, and American Robin.
*Out of the lagoon 207 visits for which censusing was done, Common Tern was present 12 times (5.8%) with a total of 49 birds.

Our next three scheduled field trips:  Mt. Piños Birds & Butterflies, 14-15 June, 8am; Malibu Lagoon, 22 June, 8:30 & 10am; Malibu Lagoon, 27 July, 8:30 & 10am.
Our next program: Tuesday, 7 Oct., 7:30 pm. To Be Announced.

Despite cries from “those of little faith,” the Mallards are doing quite well, thank you. (R. Ehler 5/25/14)
