Drama at the Dutch Peregrine Falcon Nest

Wildlife News
People from all over the world have been watching events unfold at the Peregrine Falcon Nest in Noord Brabant, The Netherlands, via the Live Streaming Video. Two cameras were installed in February, 2007: one inside and one outside the nest box.

Three eggs were laid. Before they were hatched, a female falcon entered the nest while the father was brooding the eggs. He flew away, she inspected the eggs, then left, never to be seen again. The three chicks hatched April 14 and 15. On April 22 another female falcon arrived and attacked the mother. The fight began at the nest box and continued in the woods a short distance away. The mother was driven from the nest and possibly mortally wounded because she did not return. The father then took over the responsibilities of feeding and raising the chicks by himself. The chicks were 7 and 8 days old, much too young to be without a mother.

The Bald Eagles Sleeps

Victoria/Sidney Nest The Sidney Bald Eagle Nest cams are giving some insights into Bald Eagle behaviors that were pretty much impossible to observe before the introduction of streaming videos of a Bald Eagle's nest. One such observation that has been recently discussed in the Hancock Wildlife Discussion Forum is characteristics of the eaglet's resting and sleeping behavior. The Sidney Eaglet seems to prefer to nap and sleep directly in front of the close up camera, giving us a great opportunity to observe in detail.

Ostrich has noted that when the eaglet first settles down to rest, he will repeatedly put his head down on the nest bowl but rise and look around after only a couple of seconds. This pattern will repeat a number of times. After gradually settling down the eagle will finally appear to go into a sleeping mode for much more extended periods however, will still seem to be quite alert if a sudden sound is heard and will cause him to rise and look around instantly. Naturally the question comes to mind - is this behavior the result of needing to be alert to dangers?

Ostrich posed the question, "I wonder if there are any general differences in sleep patterns between birds and mammals"?

AJL answered saying, "One comparative study found differences in rapid eye movement sleep (in the study birds, REM sleep time was 10 to 25% lower than in mammals). When the eagles were incubating, some viewers mentioned Dad sleeping with one eye open; I don't know that regular "one eye open" sleep has been confirmed in eagles, but it has in avian species that sleep on the ground. A paper in the Journal of Behavioral Brain Research presented evidence that birds control sleep and wakefulness simultaneously in different regions of the brain. Only birds and aquatic mammals (presumably so they won't drown while sleeping) do this."

Soundguy posted a video which illustrates some of the sleeping behaviors. Ostrich explains that at the start of the video the eaglet appears to be fully asleep. However, once the parent vocalizes nearby he reacts very quickly, going from a sleeping state to an alert state almost immediately. Video can be viewed at:

Skipper has posted a Video named "The Siesta" which captures napping behavior

Sounds of a Bald Eagles Nest

Victoria/Sidney Nest *Sounds of a Bald Eagles Nest*

The Bald Eagles Nest near Sidney has not only two camera's which provide streaming Live Video but also a microphone which is allowing detailed sound recordings of the Eagles' various calls and other sounds in and close to the nest.

Soundguy, one of our moderators on the discussion forum, is monitoring and recording these sounds and has posted voice prints, video/sound clips from this nest and also comparison sound clips from other nests.

*First recorded Feeding of a newly hatched chick * can be heard in this two minute edited clip

*Comparison of the Hornby Eagles Chatter with the Sidney Eagles*:

*Sounds of The Intrusion, where the Sidney Eagle pair protect their nest*. As many as four eagles are involved in a very loud battle at the nest:

*Three waves of Canada Geese fly very close to the nest, and the brooding eagle screeches many warnings*:

*Sounds of a Woodpecker near the nest*:

*Female Eagle communicating with her young eaglet*. This vocal fingerprint is unique. We've not heard an exact duplication anywhere, anytime from the female. Now we have a positive make on the female talking directly to her young eaglet, which will aid immensely in the study of eagle language and communication.

The above is just a sampling of some of the recordings captured so far this season. Recordings of the sounds from the Sidney Nest will continue throughout this nesting season. To read the full discussion and see other links to the recordings go to the Hancock Wildlife Discussion Forum, Sounds At The Sidney Nest

Following the fledge and departure of the Sidney Eagles this fall, we plan to create CD's and/or DVD's to store the eagle communication audio from this years as well as last years activity. These will be dated, and run chronologically.

Streams and Eggs and all - an update from the trenches

Wildlife NewsIt has been a hectic April and it's not over yet.

First of all I want to appologize to those trying hard to view the cameras through our Windows Media server. We have had to cap the amount of traffic it can put out due to the cost of the link. At the current cap it should easily handle about 90 simultaneous viewers but has at times had over 300 trying to share its link. This has nothing to do with how capable the actual server is - it is capable of serving well in excess of 3000 simultaneos sessions if we opened up the flood-gates (network bandwidth) but at that rate it would be costing the foundation something over $10,000/month which we simply don't have at the moment. We're looking for sponsors to step up to the plate, and the advertising revenue is starting to climb, but it appears that this simply won't happen in time for the onslaught we expect once chicks appear.

In fact, we've pretty much known this all along - that we were caught in a catch-22 situation where the ad revenue wouldn't rise unless more people could view, and more people couldn't view until the revenue rose to pay for the added bandwidth - so we've been working on several fronts to address this.

Neokast Media Network Streaming - All Members! (updated)

Wildlife NewsHancock Wildlife Foundation is pleased to announce that Neokast Media Network has accepted our cameras as a major part of their beta test for their new peer to peer video streaming service.

David Hancock and I recently met with many of the Neokast people at the Voice/Video on the Net show in San Jose (March 20-22) and came away with an agreement that we would be amongst the first content providers in their roll-out. Since then we've been working with them almost daily to get things in place.

Starting the week of April 2nd, Neokast began adding testers (your truly included) to their system in a staged roll-out of their services. I've had a stream from their facility up and live almost continuously since April 5th, and it has worked flawlessly.

As of April 7, 2007, our administrative people were added to the list, and as they gained experience over the next couple of days we added our moderators, then some of our members.

As of today, April 17th, we are opening up the Neokast viewer (install here) to all members of our site and have opened up the Neokast discussion topic to all members of our site.
