More on the nestlings, 4 nests

It's been only a few days but checked the four nests again. Only one new egg and the nestlings still have eyes closed.

South Side

Box 2  has the same four eggs. Put some tape on the pole to stop ants, as we had a problem there last May.

Box 7 still has just 3 eggs.  The male of that pair was in a nearby locust tree

Box 9 not far away, the closest I have had two pairs of bluebirds. It has the nestlings inside and a female standing by, She was not currently feeding as they usually nap at noon.

Inside, five nestlings in a pile, the same two begging I presume.

Trying to add a video clip here:

North side

Here is the pair of bluebirds. The nest has 4 eggs.

Swallows have a nest next door.

Four Bluebird Nests, one hatched

Much like last year, we have four nest boxes with bluebird eggs. And like last year, three good nests are on the South side and just one on the North side.

South Side

Three nests are active. The boxes are numbered, but not very well to see. As you cross the bridge to the prairie, the path goes right by two boxes before joining the wlak-bike path. The very first box looks like this and has 5 eggs and had a female incubating this week.

Then further West on the gravel path we have a nest with I think 5 nestlings. There were 5 eggs last week and they were sleeping in a pile until the camera flash went off and two woke up to beg food.

The third box has 3 eggs so not quite the full 4 or 5 yet.

North Side

Box 13 has 4 eggs. Walking past the school house, the boxes are numbered and can be seen off the service road or maybe the school side. I forget what side the the number can be seen from.

Swallows

I have a good idea of where the swallow nests are. They are best left to hatch and then estimate a count. They dive bomb my head if they have claimed a box, even if it has just a nest with no eggs. One has eggs. I also know what boxes are empty. More swallows will claim them.

First Eggs and Nests of 2017

NATURE CENTER SIDE

The North side boxes were numbered and some moved to new locations along the maintenance road. The very last three boxes had nothing. The rest have either swallow nests started or in one case a grass nest by bluebirds. No eggs in it yet.

SOUTH SIDE

The south side was burned by the staff and looked barren a month ago. Some plant life is returning. The birds are fine with it. Swallows only catch flying insects.

Bluebirds like some trees like this around for roosting and waiting to find pray on the ground. One pair has selected this black box that is on a rather tall pole:

It had the full five eggs. I believe this is the male of that pair on a locust tree branch:

One more pair of bluebirds seems to have a nest in that middle part. No eggs in it.

SWALLOWS

Near the Western end of the new gravel road there is a fluff clutch of swallow eggs. No bird was incubating on it. They may wait a week or two and the eggs may survive.

Another pair had built a full nest that had been taken over by ants. They were angry at me for taking it apart and destroying the ants.

I ended up putting reversed duct tape on the pole, as well as the neighboring pole.

Lastly, a nest box had been driven over by workers with a tractor. It had a grass and feathers swallow nest in it but luckily no eggs.

Signs of Nest Box Selecting

I met someone that asked about the bluebird boxes today, and she shared some experiences. Usually the conversation starts with "bluebirds, aren't those nasty?" No, those are Blue Jays! Then I explain that these are small thrushes and have blue and orange. Then the person responds, "oh, I've never seen one," We try to look for them but see only swallows.

I only went through the North side 18 boxes today. pairs of tree swallows are flying around the boxes and some pairs seem to have chosen a box and are defending it.

This is box 9 in the middle of the prairie. The swallows do not lay eggs till May, but may build the nest this month. In any case they guard it against other swallows.

One pair of bluebirds has claimed a box near the school house on the top of our prairie. The trees of the golf course fence are nearby. Of the two boxes, they chose the more worn out one, 13. The new looking box 14 behind it may take a year to have appeal. It is also unncessarily large. I hope they stay.

 We only had little success on the North side with bluebirds last year. The two boxes nearest the Nature Center, 1 and 2, are claimed by house sparrows.

Almost Spring

I have another blog on birds of Nebraska. Here is the last entry.

A few shore birds have been located. Wilson's snipes and both yellowlegs.

Pelicans are migrating through and both horned (molting, bottom picture) and eared grebes were seen at Wagontrain recreation area.

This is the time we see ducks in all kinds of puddles before they settle into secret nesting areas or move North.  Ring-necked duck, blue-winged teal.

March Readyness

There are actual signs of bluebirds around the boxes. First I had a check of the North side and was surprised to see a tree swallow. It was merely flying around. The bluebirds and swallows start to have a conflict with the boxes in April. On the North side there was one box near the Nature Center claimed by house sparrows. I will not do anything with that, I doubt very much any bluebirds will nest in the nearest other box. But it needs monitoring.

On the South side I had a surprise as well. They had done a burn. Boxes 1 and 2 in the burn area:

Near these boxes was one male bluebird. Click the picture to see him in a boxed area.

The detail shows him at the same branch. Further along the bike and walking trail no boxes had burned. The entire prairie was burned. Only 5 killdeer were visiting.

Cleaning out boxes and new numbers on North Side

I moved a few boxes in the fall to the service road behind the school house and the boxes had odd numbering in any case. My improvement was to number them along the route in the order I normally check them. The numbers are a bit conspicuous but I can also get a picture of parents and nestlings with a numbered box now. There were no bluebirds today. Box 5 shows the example of the new numbering.

A few boxes are now unpaired, such as 15 which was moved out of the way of Prairie Jazz and the last box, number 18. That is behind these two along the service road.

I will see some bluebirds around the boxes by March. Three pairs typically on the South side. it will be interesting to see if we get more bluebirds on the North side than last year, now that the boxes are a bit more away from people paths. The tree swallows do not seem to mind people. They fly over the ponds for the insect food so this North side is convenient for them.

I moved a box off the parking lot area that had house sparrows. The house sparrows will claim maybe one box near the Nature Center. They also fight for the purple martin houses on the tall pole.
