Natalia,
It is quite possible that is what you heard. Whatbird.com is a great web site that is easy to navigate and covers just about every bird. It also has a sampling of sons and calls for each species.  Keep an eye out for that bird and hopefully you'll be able to confirm your sighting! But when it sits still, you probably won't hear it utter a sound, and they can be very good at blending into their surroundings.

Good luck, 


Jane S.

Subject: Re: [VTBIRD] Possible Black-crowned Night Heron








Around 7:00 tonight we heard a strange call, almost like a bark, coming from a 
group of black locust trees near our house.  The trees are about 200' from a 
large swamp.  We got a quick look and then it flew over our house (away from the 
swamp) and landed in a group of trees about 400' from the house.  After looking 
at our bird guides and a CD of recordings we think that it was a black-crowned 
night heron.  It would be a life bird for me and my dad.
