Malibu Lagoon |
People come to the Santa Monica
Mountains to be with nature, to get away from the concrete jungle that is Los
Angeles. They know wildlife lives here, too, that squirrels will be their
neighbors, and that coyote & owls will call out in the night. But
there are many critters that are rarely seen, even by old-timers. Sometimes it’s because they are nocturnal. Other times it’s because of
dwindling population from loss of habitat or poisonous rodenticides. Some animals avoid humans altogether by living in the less populated parts of
the mountains. Then, there are critters we can’t see because they are camouflaged.
You can be looking right at them and not even know it. So it is with Invisible
Birds.
Invisible birds, are so rarely seen, so how do you know they are there?
Why, by their calls.

The Virginia Rail (Rallus
limicola) and the Sora Rail (Porzana carolina) are marsh birds
found at the Malibu Lagoon. “Thin as a rail,” the Virginia Rail has a
compressed body, an interesting survival adaptation by this elusive wetland
bird, that makes it difficult to see them as they slip through the marsh
tule reeds (Scripus acutus Tule).
The Virginia Rail prefers to evade
intruders by running through marsh vegetation where it is safe rather than
flying away. When it does fly, it only flies a few yards before disappearing
again, once more invisible in the marsh.
The Virginia Rail’s Latin species
name, “limicola,” means “mud dweller.” True to their name, Virginia Rails
usually nest in muddy areas in shallow fresh water marshes with new growth,
rather than salt water marshes.

The Sora Rail (Porzana
carolina), also found in the Malibu Lagoon, is a small, secretive bird.
It’s wonderful, musical “whinny call” can be easily heard from deep within the
tule reeds, but trying to see the little bird is a different matter as it is
well camouflaged in the reeds. “sor-AH” “sor-AH”

Another Invisible Bird is
the Common Poorwill (Phalaenoptilus nuttallii).
The Common Poorwill is not a rail and is not a marsh bird. They are nightjars
of the arid West, the smallest members of their family. They prefer the dry
grassy Malibu canyons like Zuma and Trancas Canyons. Their cry of “poorwill” is
familiar to residents there.
It requires keen perception to see
the Common Poorwill, as they look just like “Dirt and Twigs”. Great camouflage! They won’t run from humans if you happen to approach; they assume you can’t
see them!
Along with the sounds of Hawks, Owls and Coyote,
the calls of these birds join in the magical symphony of the Santa Monica
Mountains. Whether seen or unseen, bird calls give us an unmistakable sense of
place. You don’t have to see the Invisible Birds
of Malibu to know where you are.. It is all in their song~
There’s a symphony going on where
you live, too. Take a moment to stop to listen and enjoy each member of
the orchestra. We’d love to hear ‘what’s playing’ in your back yard.
