<div dir="ltr"><div class="gmail_default" style="font-size:large;color:#073763">There are documented cases where fireworks displays have wreaked havoc on seabird colonies. A Brandt's Cormorant colony at Cape Viscaino, CA was once decimated by gulls after fireworks flushed the adults off the eggs and chicks. I've heard of similar concerns at other coastal locations. I assume the fireworks must have been really loud professional ones pretty close to the colony. </div><div class="gmail_default" style="font-size:large;color:#073763"><br></div><div class="gmail_default" style="font-size:large;color:#073763"><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Jul 8, 2024 at 6:32 PM Michael Price via Tweeters <<a href="mailto:tweeters@u.washington.edu">tweeters@u.washington.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Hey tweets<div dir="auto"><br></div><div dir="auto">Any animal with its eyes on the front of its head which looks at you directly and maintains direct eye contact can safely be classed as a potential predator. If such an animal walks or flies into your panic-radius, you'd be best outta there as quickly as possible, just to be prudent. So eye contact alone may trigger panic/precaution flight. I have often walked past a crow (and this applies anywhere in the city) on the ground at a distance of 4 ft/1.1 meter as long as my face is averted and I'm side-eying without the bird flushing—very wary, yes—but the instant I turn my head and look at it directly, that crow is *gone*.</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">An animal's characteristic panic-radius determines the minimum distance one can approach it. Dennis's flicker is often a ground-feeder so needs an ample open area for visibility; anything within a certain distance will trigger escape flight. As an extreme example, Surf Scoters will flush at any approach on the water of about 75-100ft/23-30 m (🤬kayakers) and completely vacate an area, sometimes not stopping for several miles/km, while Barrow's Goldeneyes sharing the same littoral waters allow closer approach and, if evicted, unlike the Scoters will simply return to their feeding/resting area after the intruding agent have left. Same for land birds at a feeder: chickadees and bushtits allow much closer approach than juncos and finches, and some scavenging bird species of the Taiga and tundra tend to have very short to no panic-radii at all—food's too short, they can't afford one.</div><div dir="auto"><br></div><div dir="auto">best wishes, m</div></div>
