I recorded several owl-call hoots using a quaker boy owl hooter and gobbler locator. I recorded this file on a tascam dr-100mkii using an mxl r144 ribbon microphone.
Unknown bird species from bellingham washington, recorded with a zoom h2. If you know what kind of bird this is, i would love to know in the comments :).
Bird call in north central massachusetts, in a wooded area within a city. Sound is up in a tree. I suspect it is baby bird calling to a parent, and the softer response is from a different tree. There is a third bird, possibly unrelated.
