Sunday 2017-04-23 (10:00-11:00): More real Easter eggs in "our" nestboxes!!!

Box #1: Two small sticks inside the box and droppings on the roof. Otherwise, still empty.

Box #2.

Box #2: Some shavings inside the box, but otherwise still empty.

Box #3.

 Box #3: Tree Swallows were seen entering/exiting the box. More feathers have been added to the nest, but there were no eggs yet.

Box #4.

Box #4: There is a new nest of straw, with one light-blue egg (probably a Western Bluebird)!!













Box #5: Empty. Removed a small Vespid and nest in the upper corner.

Near Box #6; We are being watched.

Box #6: Nest present, with feathers, but no eggs yet. A pair of Tree Swallows sat together very nearby while we checked their box. We were also repeatedly dive-bombed.













Box #7: Empty. This box is shaded in the morning, which may not be ideal.

Box #8; Three Tree Swallow eggs.

Box #8: Tree Swallows were seen entering/exiting the box, as in weeks prior. But now there are now three small, very white (almost translucent), and tapered eggs! The Tree Swallows returned to the box as soon as we moved away.

Box #9. The eggs looks white in the photos, but they were blueish.

Box #9, four eggs.

Box #9: This nest has a very deep cup, and two more little blue eggs have been added (making for a total of four now)! There are no feathers incorporated into the nesting material. Bluebirds were seen entering and exiting the nest. We also watched half a dozen Tree Swallows swooping around and landing on this box. One was quite interested in looking down the hole of the metal pole. The Bluebirds seemed to be sitting at and protecting the nestbox entrance quite frequently. They also sat on the vineyard stakes directly opposite the box.





















Box #10: The nest that had been started is still unchanged. No eggs present.

Box #10.

Western Bluebird Nestbox Monitoring - April 9th, 2017

Sunday 2017-04-09 (10:00-10:30): A beautiful sunny morning, with wisps of fog and clear skies after the recent rains. And, we have our first nests getting started!

Box #1: Empty. Drilled some vent holes.
Box #2: Empty, with a few small sticks. We knocked out a small Vespid nest and drilled some vent holes.
Box #3: A nest has been started! Many of the blue feathers that had been nearby on the ground last week had been incorporated into the nest.

Box #3 with the start of a nest.

Box #4: A pair of blue birds were seen flying away from the nestbox as we approached, with one having come from inside the box. We removed a small Vespid nest, applied more lye soap to the top corners of the box interior, and drilled some vent holes. Otherwise, the box was still empty.

Box #5: Empty. Vent holes were added.

Box #6: There was a piece of straw hanging out of the hole (very cute!). Inside, a straw nest had been started. We added a top vent hole.

Box #6.

Box #7: Empty. We drilled a vent hole in the top.

Box #7.

Box #8: This is still the most active box, with lots of Tree Swallows swooping about. Tree Swallows were seen bringing nesting material and entering the box. Inside the box, a nest had been started. A Tree Swallow brought nesting material as soon as we moved a little away from the box. Bluebirds and many Red-winged Blackbirds were in the nearby trees.

Box #8.

Box #9: There were a lot of White-crowned Sparrows in the nearby bushes. There was a fresh bird dropping on the outside frount of the nestbox, and inside was a very well-developed nest of mostly straw.

Western Bluebird Nestbox Monitoring - April 2nd, 2017

Sunday 2017-04-02 (10:00-11:00): We continued our new Sunday routine today, enjoying another gorgeous visit to the vineyard to monitor nestboxes. There was a bit of fog when we first arrived, which is so characteristic of this region.

Today we more properly labeled each box, and remembered to take measurements of the hole diameter and compass bearing.

Box#1: Empty, but two small twigs had been brought in. This is the box that I thought I saw a Wren on top of last week.

Box #2: Empty.

Box #3: Oh dear ... there was a dense cluster of blue feathers on the ground below the box. Feathers and fresh droppings were on the top and sides of the box, and there were a few pieces of straw inside the box. This box may be too near the vine post, thereby enabling predator access?

Evidence of a predation event at the base of Box #3.

Box #4: Empty.

There's been some new trees planted near boxes #4 thru #8.

Box #5: Empty, but two Vespids were inside.

Box #6: There were a few pieces of straw inside the box, and fresh droppings on the box roof. We removed a Vespid, and applied more lye soap to the inside of the box.

Box #7: Empty, but a single Vespid flew out of the box so we re-applied lye soap to the inside. This box and possibly a few others need a few more ventilation holes drilled.

Box #8: Empty, but this box had several pieces of straw inside and Tree Swallows were seen bringing nesting material to the box.

Interior of Box #8.

Box #8.

Box #9: Empty, but there was evidence of recent bird activity: fresh droppings and a few pieces of straw.

Box #10: Empty, but a few pieces of straw had been added to the box.

We had quite a thrill when we spotted a Bullock's Oriole!, in the tree near Box #8.
