Mallard female touchdown (Ray Juncosa 4-25-21)

As with March, this was a Sunday morning affair, rather than mid-week. Although the surfers were out in force, cool temperatures for April kept sun-worshippers off the sand. Eleven masked and vaguely distanced birders appeared.

The Canada Geese have definitely found the lagoon a friendly place to nest. At least three pairs nest on the southeastern brushy sand island; perhaps the fourth pair as well. This island has lots of brush and is the farthest from solid land. When the geese crouch lie low, they’re hidden from people on the path. From an Osprey-eye’s view, overhead, they’re obvious, but fortunately for them Osprey aren’t interested in geese.

The noisy and busy Northern Mockingbirds were easily seen. This one’s face was probably buried in pollen. (C. Tosdevin 4-25-21)

Ducks are leaving for the north. Our March 22 trip counted 9 species and 100 birds, now down to 5 species and 55 birds. Coots also dropped from 235 to 75 birds, but gulls and terns rose 252 birds in 8 species to 531 birds, also in 8 species. Most of those are the 395 recently-arrived Elegant Terns, back from wintering in Mexico. Migrant passerines were almost totally absent, with a lone male Hooded Oriole the sole representative. One or more pairs of Hooded Oriole have nested in the palms and other trees around the lagoon and Adamson House for the past 15 years, excepting 2007.

Brant geese are regular visitors at the lagoon. Recorded them 45 times since 1979 and average 3 birds per visit, they’ve appeared in all months, are least common in Oct-Jan and most common in May.

Western Sandpiper (C. Tosdevin 4-25-21)
Both birds well on their way into alternate plumage.

The high tide of +4.83 ft. at 8:43am kept most of the rocks well-covered, so no Black or otherwise Oystercatchers were seen, unlike the previous four months.

Semipalmated Plovers regularly appear in April on their northward journey back to the Arctic. The only years we’ve missed them in April is when we weren’t there, as during the 2020 pandemic. Our 29 birds this time is bested only by 35 birds on 4-23-06.

Semipalmated Plover, regular in April. It’s hard to see those semipalmated toes. (C. Tosdevin 4-25-21)

We don’t get many Dunlin at the lagoon, I’d guess it has something to do with the vertebrate selection around the lagoon. Whatever the cause, for 1979-2021 I’ve recorded them only 27 times, for a total of 51 birds. 35 of those birds were fall migrants in Sep-Oct, 7 were spring migrants in April, and the remaining 9 birds were scattered over 4 months, 2 in May-Jun and 7 in Nov-Dec. This year’s bird is well on its way into alternate (breeding) plumage.

Our sole Dunlin (C. Tosdevin 4-25-21)

The Snowy Plovers are gone. Grace & Larry reported 20 on 3-20-21, we had 23 on the following day, but on 4-12-21 G&L had none. The beach is very wide, but very low. Even ordinary high tides can send waves almost all the way across and into the lagoon.

The outlet channel was right up to the rip-rap protecting the Adamson House fence. We clambered over the rocks and explored the property. Most birds were more of the same – hummingbirds, Song Sparrows, Black Phoebes, but Chris found a beautiful brightly-plumaged male Hooded Oriole in a tree. A few minutes later we spotted the Dunlin back on the beach and Chris made his way back to the beach to get the photo above.

Male Hooded Oriole (C. Tosdevin 4-25-21)

Birds new for the season: Brant, Semipalmated Plover, Dunlin, Elegant Tern, Peregrine Falcon, Spotted Towhee, Hooded Oriole.

Many thanks to photographers: Lillian Johnson, Ray Juncosa, and Chris Tosdevin

When Snowy Egrets aren’t wading, you can see their yellow feet.
(R. Juncosa 4-25-21)

The next three SMBAS scheduled field trips: Who knows? Not I.

The next SMBAS program: We may have a June Zoom meeting. Watch for announcements.

The SMBAS 10 a.m. Parent’s & Kids Birdwalk remains canceled until further notice due to the near-impossibility of maintained proper masked social distancing with parents and small children.

The 10-year comparison summaries created during the Lagoon Reconfiguration Project period, despite numerous complaints, remain available on our Lagoon Project Bird Census Page. Very briefly summarized, the results unexpectedly indicate that avian species diversification and numbers improved slightly during the restoration period June’12-June’14.
