Cobirders, 

 
For those of you who have dismissedthe postings about the Royal Tern, you may 
be missing the chance of a lifetime.This monarch has been displaying his royal 
plumage and beak to several of us atBarr Lake off and on since the discovery 
July 29 by Steve Mlodinow. Since then,it has shown off its bright orange bill 
to many interested gawkers. Only thethird time it has ventured into Colorado, 
this sovereign’s normal United Statesflying is only along the eastern and 
California coastlines. Males and femalescan distinguish each other, 
fortunately, but we humans can’t tell them apartwithout some, ahem, invasive 
procedures. What we can say is that it is an adultbird who has put away its 
breeding plumage for the season. That was not adifficult change of costume, as 
it basically consisted of switching to alighter weight hat. Normally rare birds 
are the juveniles who haven’t yetlearned how to use their GPS devices, as 
birds’ navigation systems are toocomplicated for us humans to figure out. 
 
To pay homage to the visitingroyalty, go to the Barr Lake Visitor Center 
parking lot. (Parks Pass required).Walk west across the bridge and into what 
you remembered to be the lake. Thiswill be easy, as the reservoir is now half 
beach. Walk until your feet get wet.Start scanning sandbars and other landing 
zones. Or, you may be lucky enough tocatch the tern fishing. Terns are the 
sleek members of the gull family. Notethe pointed bill, wings and tail, which 
is forked. The royal is much moreacrobatic than the slightly smaller 
ring-billed gulls with which it willassociate on the beach. The exciting part 
is watching it plunge dive for itsdinner, going headlong into the water. 
Royalty, you know, dislikes stooping toeat commoners’ food, such as beach 
garbage.
 
Barr Lake, which also houses theheadquarters of Rocky Mountain Bird Observatory 
at the northwest corner of thelake, has been a special place in Colorado to see 
birds. A total of 18 firststate records have been seen there, but this is the 
first time Barr haswelcomed royalty. So who knows, you might miss a tern and 
luck into somethingelse. 
 
Enjoy your visit.
