The Herring are Running

At this time every year an amazing phenomenon takes place. Herring, alewives and shad (all the same kind of fish) return from the sea to fresh water to spawn. They come by the thousands and much of their journey is uphill.They swim through the creeks and rivers and up the waterfalls....
They hope to get by the gulls and herons that come to feed....
They hope to reach this place or places like it.
Herring are anadromous, meaning they live in salt water as adults but spawn and are born in fresh water. Late in the summer and in early fall the young herring, known as fingerlings, will return to the sea.
These pictures are a bit murky but give you an idea of the numbers of fish passing by and the 'run' has only just begun.
There is a moratorium on taking herring from the runs where I live since the herring population, once robust and enormous, is now severely depleted, most likely due to large factory boats taking them by the millions....

This herring run is in Brewster.

Frogs in the Bogs....

Two of these frogs are bullfrogs and one is a green frog. Can you tell the difference? Sometimes people think because one is bigger than the other that it must be the bullfrog but remember that bullfrogs start out small and green frogs can get pretty big.Often their markings are very similar. Some are dark, some are brighter green, some have blotches and spots or look warty....in both species. Frogs tend to be darker in the spring which helps them camouflage themselves in the darker water. As the greenery grows and the overall environment seems lighter the color of the frogs will also lighten up a bit.
Check out the ridge or line on these frogs. On one frog that lateral ridge goes down the two sides of the back. On the other two it just curls around the tympanum (big ear drum).
The top and bottom frogs are bullfrogs and the one in the center is a green frog. Bullfrogs have the ridge circling the tympanum and green frogs have the two ridges down their backs so no matter how big or small or how spotty or green they are, that is how to tell them apart. Special thanks to Mary Alexander for the use of her green frog photo. All the frogs I photographed the other day were bullfrogs.
