Green Herons in flight (Aug, NJ).

Soft cuks, indicating mild agitation (July, PA).

This call appears to be used as a contact call, as between these two birds (egrets in background)(Feb,FL).


Interaction between two birds, one flying over a perched second individual (quieter end notes)(Aug, PA).

Faster calls, almost a rattle

"ee-korr", a soft call that probably represents the song (May, PA).

Black-crowned Night-Heron (Canada Geese in background, May, NJ).

Black-crowned Night-Herons near roost and calling in flight shortly before dawn (Apr, NJ).

Great Blue Heron (Aug, NJ).

(Feb, FL)

Bird in flight (Aug,PA).

In flight (Mar, PA)

Nocturnal flight call (4.05am, Sep, PA).

Great Egret calls are a low croaking (Feb, FL)

Birds in flight (Feb,FL).

Flock of about 50 Great Egrets (July, DE).

(Jul, NJ).

Snowy Egret calls (Feb, FL)


Interaction between two birds (Feb,FL).

call in flight (Feb, FL)

Snowy Egret male courtship call, a bubbling vocalization (May, NJ).

Little Blue Heron adult (Feb,FL).

Little Blue Heron immature (Feb,FL).

(presumed based on similar xeno-canto recordings as not seen, Feb, FL).

Tricolored Heron (Feb,FL).

The smaller herons are difficult to tell apart, but to me Little Blue often sounds raspier, like a Starling alarm, Tricolored croakier with more separated notes like Great Egret, and Snowy Egret raspy but changing in frequency.

Least Bittern calls were great education. Also the BC Nightheron and Bittern calls are very different. i will try to remember it!
