Introduction

Our lab would like to understand the grammar and meaning of bird songs. Bird songs are not random; they do have rules for putting notes and phrases together. We would like to characterize those rules. Recent advances in sensor arrays, computation, and computational linguistics finally make this long-sought goal achievable. The approach taken by our laboratory is to: (1) collect a large amount of bird song recordings from hand-held or acoustic sensor arrays in a variety of natural settings; (2) process the data by software, some of which is recent and some of which we are developing with new advances in localizing sources with beamforming, then filtering out noise, identifying events of interest, and then classifying them according to species and individual, combining that with behavioral observations when possible; (3) this information/knowledge is then stored in a large database that is shared among collaborating research groups; and (4) analyzing the recordings by computational-linguistic tools to identify the syntax of the songs. Combined that linguistic understanding with information about the context in which it occurred, our aim to explore new software methods to identify the meaning of those songs. We collaborate with ecologists, engineers, linguists and artists.

Our work is contributing to a profound transformation that is already underway: the recognition of very sophisticated signaling strategies and syntactic structures in non-human species. The new tools and methods for collecting and analyzing bird song now allow a level of observation that previously would not have been possible. We are now collecting truly vast amounts of data from previously inaccessible settings and subjecting data to previously undiscovered sophisticated structural analyses. Our work may also be transformational to computational linguistics if the natural world beyond humans were shown to have languages that are radically different from our own (as seems quite likely).

July 2014

Takashi Ikegami and Mitzuki Ota, with their students Atsushi Masumori, Itsuki Doi, and Norihiro Maruyama, with help from Victoria Vesna presented a sound installation, "Birdsong Diamond", in the Murphy Sculpture Garden. The poster is at jpg and the talk at Alife in New York City is at PDF.
Some scenes from this are in the video for the Art | Sci Nanotechnology day, HTTPS. There should be a video just for the installation available before long.

Victoria Vesna's group has been working on a new web site for the bird project. It is still not fully functional, but a version is at 9372726396
