Sue had paddled this shallow, sheltered area a few days ago, and she had found colonies of strange "moss animals," gelatinous masses called Pectinatella magnifica that form on underwater branches. So we were here to look for them, and thanks to Sue's sharp vision, we found them lurking down under the murky water.
I was able to grasp the end of a branch one colony had formed on, and lifting it out of the water, was able to get a closer look at its complicated structure. To learn more about the fascinating life forms -- called "bryozoans" -- that make up these colonies, you can visit a University of Massachusetts site that tells all about them by clicking here.
A second goal of our paddle today was to see the pretty pink flowers of Water Shield, now in bloom by the hundreds in one of the quiet bays.
Most of the Water Shield flowers were tipped with the whitish anthers of the male flowers, but occasionally we could find one that had what we assumed were the rosy pink pistillate structures of female flowers. Or at least the female phase of the flower. I'm not well-versed in this flower's reproductive strategies. This Hudson backwater is the only place I have ever seen Water Shield in bloom.
Update: My friend and fellow plant enthusiast Ed Miller has written to explain the Water Shield's fertilization strategy. Each flower contains both staminate (male) and pistillate (female) parts, with the male parts ripening first. After the stamens have shed their pollen, the flower retracts underwater until the female parts ripen, at which time the flower re-emerges to accept pollen from other plants, a process that impedes self-pollination. After the flower is fertilized, the stem retracts it under water, where its seeds will develop and be "planted" again in the mud.
We were very pleased that we'd found the two things we had come here to see, but then we came upon some plants that were highly unexpected. There's a narrow island that runs through the middle of this quiet backwater, and there we found Wild Senna growing in abundant numbers. This is only the second location of all my nature wanderings where I have found this native pea-family plant. Sue saw it first, and the sighting rendered her nearly speechless, as she pointed excitedly to the bright yellow blooms.
Wild Senna has some of the oddest looking flowers I have ever seen. They sure don't look like the flowers of most other pea-family plants.
So far, we were having a very lucky day, and we also counted ourselves quite lucky to get a nice long look at this large Painted Turtle sunning itself on a log. Neither one of us could recall ever getting this close to a sunning turtle before it tumbled off into the water. It just sat there and sat there and let us each take lots and lots of close-up photos.
To top off our day of lucky finds, this gorgeous Giant Swallowtail Butterfly landed right at our feet, where it stayed and stayed, fluttering about a little, but always remaining within camera range, with its beautiful wings outspread.
There was obviously something that butterfly craved in that mud, since it refused to leave the site, plunging its proboscis into the mud again and again.
Even I was able to take a nice clear photo of this beautiful creature, its perfection only slightly marred by a tear in one of its wings.
