NATURE CLICKS #572 - EASTERN BLUEBIRDS

Male Eastern Bluebird. Their vibrant blue feathers during breeding season are easy to spot between the trees, even under low light conditions.

Shortly after our return from Oregon I saw a pair of Eastern Bluebirds inspecting a nest box I have built for this particular species a couple years ago. I saw both, the female and the male last weekend again and my hopes grow that they may take possession of the place and built a nest. The biggest competitors are the House Wrens and the first one has already arrived. Last year a male wren stuffed a lot of loose little twigs and branches into the hole and as I later found out, all on top of a bluebird nest. The wrens are much more aggressive and the bluebirds had no chance. We have several bird boxes for the House Wrens but they have their own mind and choose whatever place they like the best. Since we had a breeding pair of Eastern Bluebirds in 2020 in another nest box I still hope it will happen again.

The colors of the female are much more subdued. After a male has attracted a female to his nest site, the female actually builds the nest. Both parents feed the brood.

NATURE CLICKS #559 - EASTERN BLUEBIRD

This story started already last year, when I built a bird box that was especially designed for bluebirds. The Eastern Bluebird is a cavity nester that may use an old woodpecker hole in a tree or post but nest places became a hot commodity after more aggressive birds, like European Starlings and House Sparrows, became more widespread in the last century. Last year one of our House Wrens used the box for a nest. The bluebirds had no chance.

I photographed this male already while it came to one of our bird baths a few days ago and I became more excited when I saw it again yesterday flying into the entrance hole of the bird box with some nesting material. The nest is mainly built by the female but the males carry bits and pieces in and out of the box to attract a female. Once the female enters the box with the male the bond is established. I haven’t seen the female yet but my hope to have an active nest in this new bird box is growing.

Today’s photo was made right out of my office window on the second floor during the early evening. I had the 1.4 teleconverter between the Sigma 150-600 S and the camera and used the full focal length of 850 mm. The tree is across from the bird box, with some open space between, and the bluebird had obviously a good eye on it. He was cleaning his feathers after I made the first click and the bird gave me about 3 minutes to work with it.

JOGGING FOR BEST POSITION

House Wren feeding

As always, this time of the year the young House Wrens are jogging for the best position at the entrance of the nesting place the parents have chosen. This time it is an old gourd that hangs from the edge on the side of our porch since many years. The wrens have used it before. The nearby wooden nest boxes we have in the front yard are not used at the moment, but might if another brood will happen this summer. I saw at least three nestlings and it will not take long until they leave the hollow pumpkin. The parents feed every few minutes and the prey they deliver into the hungry bills gets a little bigger every day.

I try to stay away from the nest while taking my pictures and employ the long lens at 600 mm focal length and crop a little bit in addition. It was too dark under the roof of the porch this evening and the speed light was used towards the ceiling to bounce some light at the birds.

It isn’t the only pair of House Wrens that feed their offspring around here. There is another brood in a nest box behind the house and we can hear some chatter from our neighbors backyard as well. We are happy to have them here every summer.

ON THE ROOF

Downy Woodpeckers

The bad thing is, the big sugar maple right in front of the house is dying, slowly but surely. Half of the canopy is already without leaves and every day another piece of bark or a branch is found in the grass below. We know we need to cut the tree down soon because there is a good chance it may fall onto the house in a storm or strong wind. It will be a sad day, no matter what.

The good thing is, the Downy Woodpeckers took the opportunity, drilled holes in one of the dead branches, and raise their offspring in the tree right now. As you can imagine, we hold the tree cutting for now.

The photographer took the ladder today and climbed onto the roof of the porch. Everything was with me, camera, long lens, tripod , gimbal head, speed light, and flash extender. Even on the roof the nest hole was still a bit higher but I found a gap between the branches to make this photo.

The Downy Woodpeckers are around here all year long and are really used to our presence. Sometimes, if I fill a feeder in the yard, they don’t fly away unless I come in a range of less than 3 feet. Both parents feed the offspring. While one is out to find food, the other one is in the nesting hole and guards it. The chance for a photo is when they have the “changing of the guard”.

Here the female downy arrives and shows the male what she had in her bill. A second later the male would leave the nest and let the female take his place. I was running out of light this evening (did I mention yet that we had another gray day with almost no sun? 😏) and the only way to shoot against the gray sky was to employ some fill flash. I left the ladder in place and maybe this weekend is another chance for some interesting moments.

STORY WITHOUT PICTURE

Barred Owl ----------

Today’s nature story from our woods here above the Little Maquoketa River Valley can’t be told with a picture due to the lack of light. The photo above is from April 26, and is just supposed to support my story. As the avid reader of my blog already knows, we have watched a pair of Barred Owls this spring and finally saw yesterday an adult owl delivering a chipmunk or mouse to a big cavity in a hickory tree only ~25 yards away from our house. We had suspected that the nest was there but didn’t really have a proof until yesterday.

This evening, sitting on the porch with a glass of wine after sunset and enjoying the mild weather, I heard a subtle whistling call and saw the owl flying away from the nest site. Looking again at the tree we saw the silhouette of a small owl. No doubt, this is an owlet who just started its branch hopping period in life. I can’t wait until tomorrow and hope to get a glimpse of this young owl. The rapidly coming out leaves will make it more and more difficult to spot an owl in the trees every day that passes by and my hope is that the owlet is at least tomorrow still nearby. Otherwise it will be like searching for a needle in a haystack…

 

HIGH HOPES

American Avocet, San Joaquin Wildlife Sanctuary, Irvine, California ---------

Every local birder I met in the San Joaquin Wildlife Sanctuary in Orange County, California a few days ago was excited to talk about the possibility that the American Avocets may breed this year at the ponds of the bird sanctuary. Someone must had posted something on social media because several people asked me where to find the avocets. That wasn’t really difficult to answer, since they were present right at the pond next to one of the parking lots. In the morning I saw only three, but later in the day I counted five birds. They bend down and sweep their bills from side to side in a scything motion along the bottom to stir up aquatic insects. Their diet also consists crustaceans and aquatic plants.

I started to understand the excitement of other bird lovers while watching a pair of avocets preparing a nest side or at least pretending to. Remember, this sanctuary is next to an airport and between extremely busy freeways and residential areas.

NATURE CLICKS #328 - TREE SWALLOW

Nikon D750, Sigma 150-600mm / f5-6.3 DG OS HSM Sports Lens

Spring is not complete without the arrival of swallows. I saw the first Tree Swallows already a couple weeks ago but now we can find them in large numbers. I spent most of the day in the Green Island Wetlands. This dead tree is standing in the water and was used by the swallows as a place to rest. There were moments when all of them took off, catching insects in flight, but after a while they always came back to this tree. The Green Island Wetlands are an ideal habitat for these swallows. There is food in abundance and many dead trees, with cavities or woodpecker holes, provide the nesting places for them.
