Vermont, Lake Champlain, Assault discussed on The Dave Gram Show on WDEV

Automatic TRANSCRIPT

He'll be back on monday you want to call in the number is two four four one seven seven seven and while we were on break we had a question right here in the studio and the question from a fisherman was to dave what about the cormorants on lake champlain seen too many of them well. It's an interesting puzzle. The you know <hes> it's as as our bird populations recovering rebound <hes> sometimes they get out of balance and the cormorant sarah bird species that you may have seen the long their long black cenex they're diving birds and they eat fish <hes> and one of the and they're unimportant and and a lovely part of our ecosystem and they can have some significant impacts on habitat they the the waste that they produce actually has the result assault of kind of causing all the vegetation to die so there really are actually one of the threats to comment turns and as their populations have really grown. There's been questions about whether they they may be impacting. Fish populations having other impacts on other bird species so there are actually efforts underway by the fremont department of fish and wildlife the u._s. fish fish wildlife service and others to figure out. How do we keep that population cormorants imbalance. That's great problem that is we have enough trouble with the blue algae and everything else so the list. I read the a little while ago about <hes> bluewater. They're called what you call. Priority birds <hes> <hes> could you talk about what that means. What does it mean to be a priority bird sure the black throated blue warbler leg it. It's it's full full. Name is a fascinating canadian example of this. It is a bird that is in terms of its national or international habitat is threatened. It has some it faces a number of risks that are causing it to be a burr that has declining populations vermont turns out to be one of its its <hes> places that it really loves to be and it's doing very well here so you might look at the black throated blue warbler and think well. It's doing fine for mind but in fact it it means all the more. It's all the more important for us to protect it here. Because it is a bird that's going to thrive in vermont and if we can protect it here we're contributing to the global population of this important species david. We have a call from pete from berry pete. Yes good morning good morning. <hes> i you mention cormorants a moment ago and i'm and just curious when i was a child in vermont <hes>. I don't remember cormorants being around here. <hes> i usually thought of them in warmer waters now. They're coming into vermont or arrived in vermont. Is that a consequence of global warming and if so are there are other birds are coming farther north because of global warming. We're gonna pitch that one right to our guest. I have no clue by thank u. P. that's a great question and i honestly don't know the answer to it but a i do know that there has been a trend in the growth in the number of cormorants there. I'm i'm pretty sure that cormorants have been common throughout vermont in the past but just not the level of the population were seen now and it could be a connected to climate climate change. There are definitely bird species that we're seeing shifts there birds that we didn't ever used to seeing vermont. They're more southern that have begun to shift their range into vermont. There's other species that are at the southern end of their range in vermont who are which are becoming less frequent. You know one of the birds will worried about for instance is the bicknell's thrush so there's no question that we're seeing changes in <hes> in wind snow melt happens when vegetation happens when there's insects <hes> <hes> <hes> blooms and all these things are connected to birds birds have thousands and tens of thousands of years of evolution that have caused them to to arrive on a specific time in a specific location and if because of climate change there are the food that they're expecting to be there isn't they have to keep going they have or they won't come as far so it depends on the species and the nature of their habitat needs but there's no question we're seeing impacts from global the global climate crisis crisis..

Coming up next
