This observation is the continuation of a previous post. The previous article can be found here Red-tailed Hawk – Nest Update 2

The female was sitting high atop the cell phone tower today when I arrived. From her vantage point she was doing the double duty of keeping an eye on her young as well as watching for her mate to return with breakfast.

Soon, the male did return, but he was empty handed. He circled the nest a couple of times and even attempted landing up close to the female. He aborted this attempt at the last second, possibly detecting the females displeasure with his lack of production this morning.

In any case, the male flew away to the north and was soon gone from sight.

Meanwhile, one of the juvenile birds decided to do some morning stretches. His fast growing flight feathers were easily visible. He was clearly beginning to take on the brown coloration of a more mature bird.

At some point while I was photographing the juvenile, the adult male returned and landed at the top of the tower right next to the female. This is when things really started getting exciting.

The male was still empty handed, so he did not stay atop the tower long. He soon launched himself into the air and did a remarkable dive straight toward my position. I was not prepared for what happened next.

The hawk zoomed by my position and briefly disappeared behind the tree I was standing next to. I expected him to continue on and possible enter the neighborhood behind me.

Instead, I heard the starlings congregated in a tree behind me call out in alarm. I turned just in time to see our male hawk crash headlong into the thickest part of the tree. Starling and leaves erupted, going every which way.

The hawk dug himself out of the tree and flew to the roof of a nearby business before I could bring my camera to bear. Again he was empty handed. The hunt had been a failure. It just wasn’t this poor hawk’s morning. And, to add insult to injury, an agressive Northern Mockingbird began to harassing the marauding hawk, and soon drove him away.

This observation is part of a weekly monitoring of an active Red-shouldered Hawk nest. The last week’s observation can be seen here: Red-shouldered Hawk – Nest Update 2

When I first arrived at the nest on this day there was not much going on. The female was sitting high on the left side of the nest, apparently alone.

Then as I watched, I was thrilled to see a tiny white fuzzy head poked up from down inside the nest. A baby hawk! The first one I had observed at this location.

The baby was active while I was present. He could be seen moving from place to place inside the nest. He was seen testing out his miniature wings.

Reportedly, this nest contains three young hawks. Right now, I can only verify the one. But, I will be back. If there are more, it should become quite obvious as the eyases age.

This observation is a continuation of an earlier post documenting observations made at an active Black Vulture nest. The previous article can be found here: Black Vulture – Nest Update 3: Baby!

This week the vultures really put on quite a show for us! We got to see an absolutely disgusting feeding of the now nearly two week old chick. Long strands of mucus covered, regurgitated red meat. Seriously gross.

We also got to see the changing of the guard. That event was quite comical, as the bird being relieved bolted unceremoniously, before the second bird even had a chance to approach the nest! Evidently, the first bird really needed a break!

On the way out, the relieved bird first stopped on the roof of the building and sunned her wings for a few minutes. We were able to observe this behavior in the reflection of the building’s windows.

Afterwards, the vulture took to the air, and after gaining considerable altitude, she joined up with two other Black Vultures. The trio then flew away together heading east.

Back in the nest, the relieving bird briefly tried to feed the chick, but the chick appeared to be full, so nothing ever came of that attempt.

This observation is the continuation of a previous post. The previous article can be found here Red-tailed Hawk – Nest Update 1

In this edition of my weekly Red-tailed Hawk nest observation I found the nest unattended by the adult birds when I arrived. I settled in for a short wait, and within 30 minutes both adults returned to the nest.

The female arrived first and landed high above the nest near the very top of the cellphone tower. The male followed soon afterward, and he was carrying breakfast. From the looks of things the male had captured a European Starling.

As the male approached, the female flew down to the an antenna near the nest. The male landed nearby, and passed the starling on to the female. She then moved down to the nest and began plucking feathers from her prey. This is when I finally got my first look at a juvenile hawk in this nest.

The eyas was excited by promise of the meal to come and began begging to be fed. Later, another young hawk could be seen jockeying with the first for position.

So, there are at least two baby hawks in this nest, and they appear to be around two weeks old.

When I first arrived the nest was unoccupied. A rain storm had passed through just an hour or so before, and I feared the worst. I was greatly relieved when the female returned to the nest just a few minutes later.

The weather was still overcast and the temperature was relatively cool(60F/16C). Despite this the female remained on the rim of the nest, and did not immediately begin to incubate the eggs. Perhaps she was allowing the nest to dry out a bit.

While she waited the male stopped by for a quick visit, and he came bearing a gift. The male presented the female with a small snake and then quickly left to continue hunting.

The female proceeded to eat the snake, and then settled back into the job of incubating the eggs.

The Video below includes a zoom-in to the nest.

This observation is a continuation of an earlier post documenting observations made at an active Black Vulture nest. The previous article can be found here: Black Vulture – Nest Update 2.

We have a baby Black Vulture! We received word that the first baby Black Vulture hatched at around 1:00pm on March 26, 2012 after approximately 34 days of incubation.

We all eagerly awaited the hatching of the second egg, but instead, we received some sad news a couple of days later. As it turns out only one of the two vulture eggs was viable this year. By March 29, the second egg had been pushed aside and crushed. There was no embryo present.

It was March 31 before we were able to travel to Denton to visit the nest. Once there we discovered the newborn vulture in the care of its mother and doing just fine.
