"I come into the peace of wild things who do not tax their lives with forethought of grief.
For a time I rest in the grace of the world, and am free." ~Wendell Berry

The Hidden Secrets of Leaves

The trees are shaking off the last of their dead leaves in preparation for winter. We usually gather them by the wheelbarrow loads and dump them in the raised garden beds and the compost pile, turning everything under so they can help improve the soil for next year's harvest.
As I've written about before, the transition to Fall is my favorite time of year. I think part of my love for Fall is due to the decline in the tick and chigger populations.
Our favorite resident female squirrel (whom we've named, "Olivia") has been a frequent visitor in this part of the Savanna - now we know why. With the leaves gone, we can see her new nest at the top of this oak tree. Unfortunately for her, the Great Horned owl has also found her nest. Several weeks ago, around 11 PM, I was out with Nikki and suddenly the GHO flew out of the dead tree to the right of Olivia's nest, sending more dead limbs crashing to the ground. We've seen Olivia since then, so I'm hoping she has decided to nest somewhere else.

As Fall transitions into Winter, it also provides me with the opportunity to cut back limbs on trees that were allowing the hawks to hide their approaches and attacks on my martins. Apparently though, not only some limbs, but some more trees have got to go, before my martins return in March.
The hawks used this corridor to come bulleting through and surprise my colony.  (the closest tree in front is 150' from my colony)
This winter, it will be a massacre where the trees are concerned. We had a tough end of season with a male Sharpie and a female Cooper's that paired up and wreaked havoc on my colony. As much as I love my martins, I was glad to see the last of them leave in August so I didn't have to watch the onslaught.
Bob and I watched helplessly as martins were snagged in mid-flight, until we put up these barriers to help deter and re-route the hawks.
I hate cutting down trees.  It just feels so wrong. But, if my colony is going to survive and thrive, I need to make some sacrifices.  It always makes me feel guilty when I do it, as I know the resident wildlife are using the trees to raise their young.
As the trees, bushes, blackberries, multi-flora rose and the other varieties of shrubs we have here have shaken off their summer and fall colors, I have started to feel a bit better about the decision to take out some trees.  To my delight, I have found that many more birds are using the dense cover provided by the leaves and brambles, than I originally thought.
In this thicket north of my house, of blackberries, multi-flora rose and buck brush, I had to look 3 times to verify the nest in the middle of the thicket.

Check out how well hidden this nest was - dead center of the photo.
Without the benefit of having eggs in the nest, it's always been difficult for me to ID nests, unless they're as obvious as a tree swallow or other cavity-nesting bird.  I believe this one is a robin's nest.
Nest #1 (zoomed in photo of the nest in the thicket above). It seems to have a combination of small twigs and grass.
Updated: a purple martin friend suggested "Mockingbird" nest. I fully agree!
In a nearby thicket to the northwest composed mostly of smooth sumac sprouts, another secret is revealed. This one is a small cup.  This nest is formed out of grass and leaves, so perhaps a bluebird nest?

Nest #2, formed out of grass & leaves. Updated! A purple martin friend suggests this is probably a field sparrow nest!
Only 75 feet south of Nest #2, I find Nest #3.  Another small cup nest, formed out of fine grasses and leaves too. It is fun to think about all the little birds I see flitting in & out of these thickets and how amused they must have been during the summer, as I passed by, knowing what secrets they're hiding from me, just a few feet away.
Nest #3, also formed out of fine grasses and leaves.
Following the trails we have on our 23 acres, I find Nest #4 another 100 feet south. Smaller than the first ones, but also built out of fine grasses.

Bob found Nest #5 which was so well hidden inside this cluster of multi-flora rose and tree limbs, that I had a hard time photographing it. But still I managed to get 3 pictures, even though I needed to stop and extract thorns and wipe away some blood afterwards.  How do these little birds do it? This nest is much different than the others - a neat little tunnel formed in the middle of a tightly wound cluster of moss.  Chickadee or tufted titmouse maybe?  Either way, a very smart and wily architect - she put a nice roof over her babies' heads too!

Out in the middle of the south field, tightly wound in the branches of this smooth sumac sprout, is Nest #6. It's so small...I'm guessing a hummingbird nest?  What do you think?
Nest #6
This one is very much a masterpiece, built to withstand the wind and rain, tightly secured to its supporting branches.

Finally, in the far south of the property, we find 3 more nests. Nest #7 was firmly stationed against this tree trunk on top of criss-crossing brambles and limbs, with what looked like bits of mud, grasses and small, fine twigs. Another robin?
Nest #7 - a bit of mud, grass and small twigs in this one.
I had to laugh at all the pictures I took of the birds' nests - almost every one of them has a stem showing in the picture with buck brush berries on them. Buck brush is one of the main staples of food here in winter, so if the kiddos hatched in these nests are seed eaters, they should be doing quite well right now!
Nest #8 - 100% built out of the native grasses in that area.
Nest #8 - I give up - ideas?
Nest #9 was found among a persimmon & plum tree grove that we've allowed to grow. Another one built out of grasses & fine twigs. Seems too small for a robin.
Nest #9 - grasses & small twigs.

I was able to find 4 more nests, but they were so deeply buried in the thickets it was difficult to get a good picture. Given the multiple predators and issues I have to deal with with my purple martins, it makes me wonder how so many of these nests actually produce surviving nestlings. Seeing the numbers of birds here on Gobbler's Knob indicates they are at least somewhat successful though.
I love surprises and I love that the birds are able to keep their secrets during the summer.  But in Fall & Winter, I get a peek into what they did during the summer and imagine all the little stories that were going on, right underneath my nose - well, underneath the leaves at least.
