Thread subject: Migration begun?

sami 08/23/07 01:28 pm The last time both juvies were seen on the nest was Saturday, the 18th. Since then, only one juvie (I think the same one) has been seen on the nest.

Has one of the the juvies left and/or an adult, too?
Tim P 08/23/07 01:59 pm I was out birding this morning Sami. At 2 osprey nests only male adults were seen, not on the nest but in the area. That doesn̢۪t mean the hens have left. Both nests had chicks on them calling for food.
I also came across a large flock of swallows and another of Grackles. In another area I spotted a juvenile osprey flying with a fish. I followed it and the bird was to dry for me to think it had caught its own prey.
Once I see the gathering into flocks which is happening in this area, its time to get outside and see what we can see. You never know what might be flying by.
sami 08/23/07 02:06 pm thanks TimP :-). These juvies grow up so fast. . .
Matt 08/23/07 04:18 pm I've also noticed some Canadian Geese flying in formation. A bit early for them though in this area.
Pamela 08/23/07 08:18 pm Lets see it's Thursday evening and I went back to review the observation board and saw that Tim P on Tuesday at 3:39 saw the female deliver a fish.
The juvies look so much alike, I've wondered if each come to the nest at perhaps different times as they are the last to leave.
Wondering why they aren't banded in this area.
Also, if more than one chick is banded in a nest it would make identification easier if they banded each chick with a different color band. Does this sound reasonable or impossible to those of you who have been on banding trips?
Melanie 08/24/07 09:49 am The nest is on a federal National Wildlife Refuge and for whatever reason, they don't band the chicks (not just this nest). There also needs to be a federally licensed bird bander to do the job as well. Whether it is a manpower issue or a financial issue or a conscious decision that since their numbers of rebounded so well that they don't feel it necessary to band them, who knows?

I don't believe Blackwater bands their ospreys nor eagles unless for some reason the right person comes in contact with the chicks. For example when they collected bald eagle chicks to send to Vermont last year, those got banded, but only the chicks that got selected for the program. The chicks that stayed behind were not banded.

Different countries use different color leg bands, and the US uses silver. There are plenty of people on the state and local levels who are determined to band just about any bird they can get their hands on, so there's plenty of banding going on. Just not to our convenience.
Sir Lance 08/24/07 03:54 pm I am glad these Osprey and the eagle an other osprey we watch don't get banded. What you don't know can't hurt you. All we know is they fly away in the fall and we hope for and assume the best.
Melanie 08/24/07 04:43 pm But what we don't know can ultimately hurt the birds, and what we can learn can help bird conservation. A great deal of that is learned is because of the North American Bird Banding Lab in Laurel, MD.

There is much valuable information to be learned from banding and it is certainly less intrusive than a radio pack.

Without banding, for example, we would not know that these osprey head down to Central America and without knowing that, we would not be able to help other countries understand the impact of endangering a species who may be in jeopardy. We would no know that osprey do not always return to their natal areas, or that they can live as long as 25-30 years or that a population is crashing.

Why be content with assuming the best when you can know and hopefully try to take steps to correct or avert problems? Ignorance in this case is not necessarily bliss.
Sir Lance 08/24/07 04:50 pm I think we know what we need to in this day and age. Correcting the problems is another story all together.. We know what has to be done, but actions are bigger than words..
lynn 08/24/07 06:56 pm Mel, I would have to say, that I think the bandind seems to have done a lot of good for our understanding of birds and their habits. We can see if there are ways to help, or in many instances to let the birds go their own way. A good for instance is the eagle just reported found dead tells the researchers why a particular bird would no longer be found in the area.

Celeste 08/24/07 07:49 pm The September 07 Smithsonian Magazine did an article on Albatross. There are orinthologists who visit the nesting spot of the Chatham Albatross, one of the 19 out of 21 different species of albatross that are crticially endangered. This species, nests on Pyramid Island, in New Zealand's Chatham Islands. Anyways, because of banding efforts to try to save this endangered species, they have found that many albatross lose their lives following the ships who are fishing at sea. Banding enables orinthologists to track their movements at sea, and in turn they discovered that fishing vessels at sea were causing and contributing to the decline of albatross. Albatross have no other choice because of dwindling supplies of fish to get their meals from fishing vessels. They get caught in the nets, and the cable wires. Scientists hope that the data they gather may save some species from extinction. Because of their findings some of the fishing vessels are taking precautions so that the Albatross do not get caught in the nets, cables, etc. As much as "ignorance is bliss", banding provides so much information and hopefully improvement that in the long run help the long term survival of a species. Another example, if it weren't for banding, we would not know that some osprey for example are shot and killed in their migration down south, and that by knowing this we raise awareness and hopefully a change in people's attitudes toward migrating birds.

I don't think we know everything there is to know. Everyday one way or another, there is always something to be learned when it comes to learning more about our wildlife. Banding is an unobtrusive way of learning many new things on an ongoing basis.
Sir Lance 08/24/07 08:58 pm I don't watch any of the nests where they tag them. I know it is for the good, but those wing tags are so hidious. Banding is enough. I wouldn't want to know the osprey or eagle I watched grow up died by some dumb bleeping beep on a high speed joy ride or a shooting spree. If they put his name on TV I may just look em up. I all ready know all the bad things that happen to our wildlife. More than a third of all humans are just so DUMB. The TV news and family and friends deaths are depressing enough.
Melanie 08/24/07 09:56 pm Unfortunately that is life; birds and other wildlife get killed every day, just as humans do. Life is messy. It is savage and it is indeed survival of the fittest. How will you handle next year if one of the DPOF chicks die? And they do. And sometimes the disposal of it's remains is not pretty.

We shall have to agree to disagree regarding banding and already knowing all we need to know from it. I'll continue wondering why brown pelicans who hatched in North Carolina have decided that Chesapeake Bay is now the hot place to be and what it is that has caused them to expand the northernmost limits of their range. Without banding we would not know that was happening or that we should look to see if there is a cause.
Sir Lance 08/25/07 07:36 am A chick dieing in the nest is different. The Maine eaglets died in a storm, but thats nature.
What I said was I wouldn't want to know some moron human murdered it.

"I wouldn't want to know the osprey or eagle I watched grow up died by some dumb bleeping beep on a high speed joy ride or a shooting spree."

People and animals die, but some humans get a kick out of speeding up death. The anger that I feel tward those kind of people isn't good. Mean stupid people suck.
I never could under stand how animals get run over in a 35mph zone. Thats not nature it is stupid careless humans.
I can handle nature. I can't handle Ignorance.
