The 2013 Generation - Part II

It was the best of times, it was the worst of times, it was a time of hope and new birth, it was a time of sadness and tragedy. That is the problem with observing nature. Some stories have happy endings, others not so much. The drama associated with observing nests, is day by day you never know what sort of story you are watching. Today's two stories cover the range of emotions.

Near the bench at the beginning of the Cross Dike trail, alongside the path, just before the trail emerges from the woods to cross the impoundments is a small crab apple tree. If it were a bird we might even call it a juvenile tree.

This tree is an unlikely candidate for a nest. After all it is hard by the trail. People are constantly walking very near. It is quite low, relatively easy access for many predators. But here a pair of Yellow Warblers decided to build their nest. About the only defenses were that the tree was leafy, and there was a branch running across the top of the nest sort of like bars on the windows to keep out vandals.

Word about the nest spread quite rapidly. Many of us feared for the viability of the nest, so we were careful not to share the location to rapidly, but news of the nest spread. Photographers, bird watchers, second graders, and casual observers descended upon the nest. Some observing from a safe distance, others a bit more closely.

We watched and we waited. Four eggs appeared. The parents continued to sit on the nest. The one day someone saw a chick.

Children can be so demanding. Sometimes moms need me time.

But more often they are nurturing and caring for their young

The warblers looked like they were on the path to success. They had avoided the predators. They had survived the on-lookers. But then the rains came. After the last photo it rained heavily, almost continuously for a day and a half. The next morning I stopped by to check the nest and they were gone, there was no sign of the chick, the nest lay empty with two eggs still inside. I felt sick. It was the worst of times.

Meanwhile, up on the Rail Trail up on a dead branch of a tree, Blue-grey Gnatcatcher also built a nest. This nest was also in a somewhat unlikely place. Normally, Gnatcatchers build nests high up in trees, surrounded by the leafy canopy. They are tiny things so they are hard to see. This nest was much lower in the tree, almost in the open, but built tightly into the fork of the branch.

We were blessed that this nest was so visually accessible. Gnatcatcher nests are beautiful in their construction. Cornell's site describes one as Open cup with high walls, made of spider webbing or caterpillar silk, covered with lichens or bark flakes. Lined with grass stems, bark strips, plant down, hair, feathers, or other fine fibers. Placed far out from trunk on tree limbs

The following photos take you through the sequence, from incubating the eggs, through feeding the young. You can see them grow in size.

Near the time of this photo, while the parents were away, I saw one of the chicks lean too far and step / fall out of the nest onto the branch. Surprised / scared it climbed quickly back into the nest. This was one of the flooding days.

I had brought every memory card I owned. I filled two cards with just Gnatcatchers. Towards the end, I was deleting "bad" photos between feeding runs trying to hold on until they fledged. But finally my cards were full, I was exhausted and had to leave. Sometime later that day they fledged, the next morning the nest was quiet....It was the best of times.

The 2013 Generation - Part I

Nothing is cuter than a new born baby. They look so adorable as they sleep, make their first noises, learn to eat solid food, and take their first steps. Even the adolescent period where you are not quite an adult, but no longer a baby can be enjoyable to watch (but not always fun to experience).

It is similar with watching birds progress from bonding, to mating, to giving birth, raising a family, to watching them enter adulthood. That's one thing that makes this time of year so enjoyable at the refuge. Each day another chapter in the drama of life unfolds.

Some of the earliest nesters are the Canada Geese. It seems like the numbers of newborns was down this year. Of course this is based on nothing more scientific than the impression of how difficult it was to cross the Dike early in the morning. One day, I caught this bit of sibling interaction. They were definitely sorting out the pecking order (literally).

Before the flooding we used to think it was hard to get views of juvenile Virginia Rails. At the time I was thrilled to get these photos of a young one running along the path. Now I am just happy that it was in that young, just bigger than the puff ball stage.

Some of us do not get good looking until later in life. This bird falls into that category. I might be mistaken, but I think it is a juvenile Red-winged Blackbird.

Down near the river the Grackles had a successful nest. It was difficult to see & photograph back in the woods, but here is one of the parents feedign a chick.

I was so proud of this nest. I saw the parent squabbling with Tree Sparrows early on over the beginning of this hole. Later, I was excited when I noticed that they had finished the hole and I thought I could see a head inside. Indeed these Downy Woodpeckers raised two chicks that fledged, one male and a female.

They selected a great place to let us watch the drama unfold. The nest was right alongside the Cross-Dike trail just before it exited the woods. Did you see it?

As they got closer to fledging the parents would no longer put their heads in the nest, but remain outside. They would get the chick to extend further and further to get the food. I didn't witness it, but sometime after the last photo I took and the next morning the chicks decided to step out and explore that outside world.

Check back again for Part II.

Potpourri

The refuge has been at various levels of flooding. Summer arrives with a vengence; it was too hot to use your computer, or then in the midst of the thunderstorms, it was prudent to have your computer shutdown. Life has been hectic and then trying - first unexpected camera failure, then car problems, finally unexpected health issues.

All that is to say, I know that I haven't been to Great Meadows as often as I would like. When I have, I haven't been able to process my photos and get them posted. Here are a few random shots from some of the visits I did make. Hopefully, it will tide you over until my next post.

Computer time is going to be very limited in the next week, but check back. I've got a bunch of nesting bird photos that I've been collecting & will post soon. Some I couldn't post because I was so busy taking the photos, others because I didn't want to bring attention to already risky nests.
