Lithobates catesbeianus

I’ve heard bullfrogs a couple of times recently (at Malibu Creek and the pond at Rocky Oaks), so got curious about them. This amphibian is invasive here, as well as in South America, Western Europe, China, Japan, and southeast Asia.

Bullfrogs are voracious, opportunistic, ambush predators. Their stomachs have been found to contain rodents, small lizards and snakes (including the young of the California endemic giant garter snake, a threatened species), other frogs and toads, amphibians, crayfish, other crustaceans, small birds, scorpions, tarantulas and bats, as well as the many types of invertebrates, such as snails, worms and insects.

Earlier this year, the Utah Department of Natural Resources began tweeting tips on how to catch and cook bullfrogs in an effort to encourage residents to help control the growing population by catching the invasive frogs for food. Bullfrogs are also used for dissection in science classes, but this demand is never going to outstrip the supply!

Would you ever eat bullfrog?

Nycticorax nycticorax

The Black-crowned Night Heron is a medium sized heron with a long head and a funny way of making its neck disappear when at rest. A juvenile was hanging out at Legacy Park this morning. I loved the lime-green legs.

These birds are among the seven heron species observed to engage in tool use. They lure or distract fish by tossing edible or inedible buoyant objects into water within their striking range. Smart!

Romneya coulteri

The Matilija Poppies are putting on a lovely show in the Park. Romneya coulteri is native to California and northern Mexico. The plant grows from 2 to 3 metres (6 to 9 feet) tall, with very large flowers that somewhat resemble a fried egg.

The flower is the largest of any California native species. It was nominated as state flower in 1890, but the California poppy won the title in a landslide.
