The eagles have landed, and now you can see exactly where.

Last year, the David Hancock Wildlife Foundation captured 10 eagles and equipped them with a GPS tracker.

After months of data collection, residents can now track the bald eagles 91裸聊视频 with daily updates 91裸聊视频 on the Handcock Wildlife Foundation website.

For the first time, residents can view a map that gives a glimpse into the daily life of a bald eagle, which can come with some unexpected revelations.

Although Hancock91裸聊视频檚 interest is in tracking local birds 91裸聊视频 as opposed to northern breeders 91裸聊视频 he said it91裸聊视频檚 impossible to tell where a bird calls home at the time of its capture.

The majority of the birds he91裸聊视频檚 tracked so far are northern breeders, which are easily recognizable by the flight patterns highlighted on the map.

The map shows a certain commonality among flight patterns, however, there are tidbits of interesting information to be picked up along the way.

An example, Hancock told Peace Arch News Wednesday, is that a few birds prefer to make a pit-stop at Stuart Island, which is located off the east coast of Vancouver Island, on the way to Alaska.

Why this particular location, and not one the 40,000 other islands along the route, is one of the questions Hancock hopes to answer with the new data.

But not all the birds he91裸聊视频檚 captured are Alaskan breeders. One that91裸聊视频檚 of particular interest, Hancock said, is a local bird that now goes by the name BACA03.

BACA03 is a Surrey bird that was injured, rehabilitated, banded and released seven years ago by OWL Rehab.

That bird, Hancock believes, is now the partner of the female that was nesting at the corner of Croydon Drive and 20 Avenue before the nest was illegally cut down last year. The nest has since been rebuilt in the same general area.

91裸聊视频淚f you look at BACA03 for just a day of messaging or a month of messaging, it91裸聊视频檚 kind of telling,91裸聊视频 Hancock said. 91裸聊视频淭hat bird is in and out of its nest every few hours. If you take only a day91裸聊视频檚 look, you can see it91裸聊视频檚 basically spending its time in and around that area. Now that its got young, it doesn91裸聊视频檛 seem to be doing that much. It91裸聊视频檚 getting enough food in a four- to five-mile radius of the nest.91裸聊视频

Another particularly interesting eagle, which clearly shows a different flight pattern compared to the other nine Hancock has caught, is TERF05.

TERF05 was a sub-adult captured Feb. 14 last year at the Vancouver Landfill in Delta. The bird was the first one was tagged by Hancock to leave the Fraser Valley.

Instead of heading to Alaska like the northern breeders, this bird took an obscure route, zig-zagging all the way to Hay River in N.W.T., where it died.

Hancock said he contacted a group of naturalists in the area, and they spent three weekends looking for the eagle91裸聊视频檚 body 91裸聊视频 and the $2,400 transmitter 91裸聊视频 to no avail.

91裸聊视频淚t91裸聊视频檚 my guessing that he was going to the basic region in which he was brought up,91裸聊视频 Hancock said. 91裸聊视频淚 suspect he came from somewhere around Hay River, that91裸聊视频檚 why he didn91裸聊视频檛 go any further. They do return to the general region when they mature.91裸聊视频

The question for the ages, one that Hancock has been asking himself for the past 65 years, is how do these birds find their way home? Particularly without the help of a coastline to follow.

91裸聊视频淲hat is it? What are the clues these birds are using? Personally, I think a lot of it is they learn geography. They have a built in tendency to go north to where they came from and, on top of that, they see other birds feeding.91裸聊视频

Hancock used an example of bird-watching off the coast of Vancouver Island.

If an eagle notices a school of herring, and flies with intention towards the fish, it91裸聊视频檚 only a matter of minutes before dozens of eagles join the feeding frenzy 91裸聊视频 despite there only being very few nests nearby.

91裸聊视频淲here the hell did they arrive from?91裸聊视频

Hancock said eagles are aware of other eagles91裸聊视频 movement, particularly if a nearby eagle is flying with intent. Intentional movement, Hancock said, is a sure sign that that bird is flying towards food.

91裸聊视频淭hey observed intentional movement, they know that the other eagle is moving towards food so I91裸聊视频檓 going to bloody well go because there will be food,91裸聊视频 Hancock said.

91裸聊视频淧retty soon, you91裸聊视频檝e got eagles who have never seen this herring ball until they get close. They moved in eight, 10, 15 to 20 miles just by observing the action of other eagles.91裸聊视频

Hancock said the Fraser Valley is the 91裸聊视频渃entre of the world91裸聊视频檚 action of eagles,91裸聊视频 and that 91裸聊视频渨e91裸聊视频檙e only beginning to appreciate how far they come from and where they go. We don91裸聊视频檛 really know.91裸聊视频

Hancock said he would like to track up to 100 birds, but at $2,400 a pop, it91裸聊视频檚 an expensive operation. He said he relies on donations, through his website, for the project.

91裸聊视频淐atching the birds is not the trouble.91裸聊视频 The trouble is that it costs a lot of money to put these trackers on. While the information is awesome, you also have to get something else that91裸聊视频檚 awesome, which is money to buy them.91裸聊视频
