Re: [Maine-birds] 2 questions

Good question.  I have thought about this as well.

I am not an expert in birding, but I observed that "kettle" of behavior over the Flood Farm in Clinton when the Golden Eagle was around.  The birds do not get freaked out by Bald Eagles.  They sure know they got freaked out by a Golden Eagle at the Flood Brothers Farm.  I wonder if a Golden Eagle was in the area. 

The gulls over a fire probably like to ride the updraft from the fire. 

Gulls doing this over open water are often an indicator that there is a school of fish like Blue Fish killing a lot of small fish.  The dead minnows attract the gulls.

Good first question, I would like to know too.

As for kettles of gulls ... food ... I have seen such behavior over dumps, burns of various types (usually smoke is visible too), and some type of food processing plant with vented odors or actual dumped remnants, even just an active farm.

Birders,  Have often wondered whilst watching hawks on Mt Agamenticus, how far away is that Kestrel that is at the limit of my 8 power binoculars.  Is it a mile, a half mile?  A goldfinch disappears a few hundred yards away.  An eagle, clearly, can be seen much farther away.  So is there a formula or a quotient or one of those math things that can give one an inkling into the distance at which an object of x size eludes viewing?

 

Secondly,  yesterday on Mt. A I watched a "kettle" of gulls roiling over the forest.  They weren't over water, and they didn't rise very high at all. But the kettle did sort of wander back and forth over a limited area, and they did so for a couple of hours.  I'm interested to know if anyone else has seen this kind of behavior?

 

Thanks,  Dave
