Yes those are Seagulls you see flying around the Highland Park Bridge in Pittsburgh

 I have a friend who came down from Erie Pa area where they have plenty of Seagulls which everyone thinks of them as a coastal bird.

Well imagine her surprise when she saw them here in Pittsburgh as she drove over the Highland Park Bridge  here in Pittsburgh during a winter time  to come an visit for the weekend when temps in Erie plunged 20 below zero . 35 degrees did not seem so bad. 

 Yes for decades now a large group of Seagulls makes its winter time home here in Pittsburgh . Thou you mainly see them at the Highland Park Bridge and Lock and Dam where river stays clear of ice occasionally you will find them down at Pittsburgh Point Park as in Picture above 

 When Lake Erie freezes over that's when you see the most gulls they come down to Pittsburgh on holiday and have plenty of fish from Allegheny River  and higher temps than Erie and much less snow usually than Lake Erie area  .

Some have decided to stay year around as they like it here.  So you can imagine peoples surprise when you see one hanging around the Highland Park Bridge .
