Top Photo: Red swamp crawfish stands its ground when confronted. On a morning following a very wet night, I encountered a crawfish hiking its way across the path adjacent to our wetlands. In typical red swamp crawfish fashion the decapod reared up and challenged me. Red swamp crawfish (Procambarus clarkii) are bold creatures, but over the years I’ve seen that boldness get them into trouble. They get eaten by frogs, snatched up by red-shouldered hawks and barred owls, nabbed byRead more

Crayfish Revisited
Top Photo: One red swamp crayfish jets away as another approaches it. I’m frequently asked about the creatures that live in our wetlands. Inevitably, the subject of crayfish, red swamp crayfish (Procambarus clarkii), enters the conversation. I ask whoever it is I’m talking to if they’ve read my blog postings on the crayfish. If not, I urge them to do so as soon as they get the chance. The following was first published in October of 2011 under the titleRead more
Taking a Bite Out of the Crawfish Population
About a month ago I decided to watch our local great blue heron more carefully. The heron can been seen daily stalking across the water, sometimes belly deep, step by calculated step. Every few minutes the heron splashes its head down into the water after some unseen (by me) prey beneath the surface. I wanted to see just what he was catching and eating out there in our little wetland. Ever since I began to see red swamp crawfish inRead more
Lost Dinner
As I walked down the boardwalk into Explore the Wild, I noticed nine or so mergansers fishing for bullfrog tadpoles next to the boardwalk at the point where in goes to pavement. One of the birds was violently shaking something in its bill. I thought it a tadpole and tried to capture an image of the bird swallowing the amphibian. I watched as the bird shook the object and then drop it in the water, apparently to reposition it forRead more
A Few More Sightings From the Wild
It’s been a while since I’ve come upon an adult Red Swamp Crawfish hiking across the path in Explore the Wild. I’d seen a bunch of the younger and smaller crawfish caught and used in Wetlands Teaching Programs, but hadn’t seen adults out and about for some time. The heavy rains of the past week brought them out of the water and on to the “road.” Last week I posted about a mourning dove building a nest in a willowRead more
The Crayfish Among Us: Part II
Our Wetlands is Changing! In August I wrote about a pile of crayfish hatchlings that I found on the path in Explore the Wild. I also wrote about how those crayfish are not native to our area and how they may be completely changing the Wetlands. The crayfish that I see and capture in our Wetlands are Red Swamp Crayfish (Procambarus clarkii). I first noticed these large crayfish with the red claws a little over two years ago. Then, it was unusual toRead more
Is that Orzo?
I know that this is the middle of August, but I’ve been sitting on this way too long. Back in March, I noticed a pinkish blob at the edge of the pavement as I drove down into Explore the Wild. It was morning and it had rained heavily the night before. As I passed the pink blob I slowed to have a closer at it. The blob appeared as though it might be a small pile of some sort of wetRead more
Walking Crawfish
It has rained the past two weekends. After a rainfall the Wetlands’ crawfish get up and have a walkabout. I’m not quite sure what the reason is for these expeditions, although I believe it to be a search for new areas to colonize by the crawfish. Since their gills need to stay wet in order to function (The gills are at the base of the walking legs) the animals can walk around in the wet grass following the rain asRead more
