Bloodthirsty Loons...

So I read an article in the Free Press the other day that a Loon can actually be a pretty aggressive bird when another Loon encroaches their territory. I came across another article online that says the same thing - I had no idea! I'll never hear the call of a loon as being that of a cry out to a lost lover as has also been surmised. It may be in fact a call to war! Loons have been known to fight to the death - piercing another loon through the chest and into the heart. I'm not sure I can look at a Loonie the same way again either.
