Silver Lining to Low Water Levels

9-27-great-blue-heron-20160911_7746The low water level of most small ponds and streams this fall has at least one silver lining, and that is that consumers of fish and other aquatic creatures expend far less energy finding prey, for it is all concentrated in much smaller bodies of water. The few puddles of water in small streams contain a vast amount of life, as do small ponds.

The Great Blue Heron has the advantage of having a varied diet that is found in a variety of habitats, so it forages in grasslands, marshes, intertidal beaches, riverbanks and ponds. While amphibians, invertebrates, reptiles, mammals, and birds are all known to have been eaten by Great Blue Herons, fish are their mainstay. They often forage in ponds, where they typically wade or stand in wait of prey in shallow water, which has not been in short supply this summer and fall. While the low water level is wreaking havoc with beavers and muskrats, it provides bountiful fuel for herons, egrets, kingfishers and other birds that forage in small ponds and streams as they wend their way southward.

    Stuffed bellies for some, not for others.

    • I wish I knew, Eliza. I asked my fisherman nephew and he said, “trash.” That’s as far as I’ve gotten with the i.d. I would welcome anyone’s expertise.

    It looks like a Catfish, “whiskers” are stuck to it’s face.

    Whiskers = barbels.

    I just noticed that the Heron’s lower bill speared the catfish, not likely to drop that meal, no wonder the fish doesn’t look happy.
