Drache Frau,

Loved your comment  "I'm sure they've never seen people like that before."   That just leads to so many thoughts and ways to go but I won't.

As far as whistling, we have to remember that being in such a location with the surroundings and canopy of the area, whistling could come from any number of different animals including birds.  They are still documenting species of birds and recording their sounds even today in South America and beyond.

Actually, when I first heard it I immediately thought that a bird was the culprit. I do wish that they would have other scientists and experts on the show. I think that they should have someone who's learned with the areas wildlife and/or cultures, who is also slightly skeptical. And that they should take more time to go over the evidence with different people. Then they could stop doing double investigations and it would save the show some money on plane tickets.

Understood.  The only problem with the areas of South America they are going to is that there are not a lot of experts in the field of birds and those available are still researching and looking for funding to further their studies.  Bird studies are so underfunded.  I mentioned elsewhere that the son of a good friend of mine relocated and has pioneered this field in Bolivia and is a noted conservationst and speaker who has lived among numerous tribes in South America.  So, while it is good they use some wildlife experts that have knowledge, especially that of the past, most of them have moved on from their jobs or have not lived life in these areas to know the nuances.  It is the newer members and experts in their respective fields that have been working with advanced techniques and are actually living in the environment and capturing information that you need to have access to for interpretation.

That being said, the recent DT episode of the thunderbird in Alaska has a rather simple explanation and it is not what the "eyewitness" would have liked everyone to have believed.  Here's a link to the Steller's sea eagle which is approximately twice the size of the eagles in Alaska.  It is believed that some of these birds have migrated to Alaska.  But, that's a story for a different thread and can be discussed there.

Trust me, they are not going back and forth to the same location.  All the location shots/investigations are being done at the same time and just edited to fit one broadcast.  They are not running back and forth constantly from LA.

Drache Frau,

No, I don't think they would give them a second thought for even a minute.  These are serious people and in an environment that could care less about a U.S. television show much less "reality" shows like DT or GH or even GHI who are looking for hype to explore ghosts, myths and legends.  These people travel in a world that recognizes their serious research and accomplishments and are not worried about getting a nod from DT or others.  The general public is not the sector they are looking to draw from and they could care less about U.S. tv face time.  In fact, if these programs were actually doing serious investigations and not just "reality tv" trying to discover the stories behind those myths and legends, they would be able to reach out to anyone in a serious research community.

I do agree it would be better to see more of their examination but really, when you look at it, there is not much "evidence" to examine when it comes down to it.  You are seeing the highlights and what they want you to see.  I seriously doubt there is more.  It looks to me that the amount of time you see them examining evidence is proportionate to what you see them collect which, sadly, is not much.
