abrupt weather changes

If a Northern Goshawk (NG) passes your zenith nor even passes by high and wide, what 2 things is that bird telling you?? The best time to look for(NG) is between 10 am. and 2 pm. This is also true for many other species of raptors. In summer, particularly August and September, the observer can stretch the hours from 10 am. - 4 pm. In winter, in the northeast, the window of opportunity might narrow to 11 am.- 1 pm. The cold temperatures have little to do with raptor flights. What inhibits their flight is wind and lack of sun light (thermals).
ANSWER: The bird is telling you the direction it is going and the direction it has come from! DUH! No really - this is such an obvious understanding - that it is overlooked. Basic to this study is - what is the bird doing and where is it heading. So, what if a NG is heading westward?
Well, the best time to observe NG for lengthy periods of time is in the mid-afternoon. These hawks love the wind, sun, clouds, and thermals. As an observer, we and the hawks want pleasant weather conditions. We might call it "free flight". So, during pleasant weather conditions the direction of the NG has no meaning, except during early morning or evening, or abrupt weather changes. Most times - the hawk is perusing the sky and landscape, leisurely. NG go to work in the morning. They will leave their winter-roosting areas of Tucson, Yuma, and Apache Junction at sun up, and will fly to their first hunting area. When NG return to their winter-roosting areas cannot be determined. It is best to say - 2 hours before sun down, or 1 hour before sun down, or at sun down - or any increment between 2 hours before sun down. So, depending on the time of day or weather conditions, a NG is telling us the general area or direction of its nesting and/or roosting site.
Now to weather changes: abrupt weather changes occur when the sky is threatening, and then there is a tornado; anytime the weather changes from good to bad, we as humans can understand; so can birds and many other animals and insects. Strong winds or rain will alert the raptors to go
toward their roosting areas; or be driven into the trees. But, what of the flip side of weather changes? The weather can rapidly go from bad to good. Such as when I am in a hurricane - if the eye passes over, there is calm. When the entire hurricane (or a front) passes through, there is usually pleasant weather.
So, when a storm comes, it will trap the raptors. It will imprison them. When the storm breaks, the sky will clear, the sun will appear. The earth and the air will warm, and the storm's departure will release the raptors. The longer the storm the more the NG will want to break away and exercise its wings and express itself. Reminder: Goshawks love the wind, sun, clouds, and thermals. It seems to me that the weather will change much more rapidly from bad to good - than from good to bad. It takes time for the bad forces to materialise.
I will give 3 of my personal experiences relating to NG and abrupt weather changes; probably within a week. Please note: I have never found a Goshawk nest - I have never seen a NG nest. I have never found the areas where NG roost (not nest) in Tucson, Yuma, and Apache Junction.
