If you want to master birding by ear, you need to know how to tell apart bird species according to the big birds sound they make. What’s the Difference Between Bird Song and Bird Calls?.It also shows that none of the other sounds were incorrectly identified as a bellbird. It also shows you the number of times we incorrectly identified a sound as that bird.įor, example the chart below shows that 70% of bellbirds in the test set were correctly identified as bellbirds and 30% weren't. These charts show the accuracy of our model against the test data for the different birds. For each bird this shows you the number of times that our model correctly identified a bird against the test data and the number of times it got it wrong. This will give you data on all your historical recordings. Once we are confident that our model is producing reasonable results we are planning on processing old bird recordings. Watch this space and please let us know if you're interested. We hope it will be cheaper and more robust that the existing bird monitors. We have been working on this in our spare time and hope to finish this after we have completed the hardware design for our new thermal camera. The cheapest phones we can find now would push the price of the bird monitors up considerably.įor many years The Cacophony Project have talked about developing the bird monitor hardware ourselves but we have never been able secure funding. The reason for this is that we have been unable to source cheap android phones. You may have noticed that we have stopped selling our existing bird monitor. This camera is available for pre-order now New bird monitor If you buy a camera you will hopefully have a bird monitor as well. We intend to add the ability to use the camera as an audio bird monitor at some stage down the track. Our new thermal camera (which is cheaper and better than our old one) includes a microphone. We are about to start working on these improvements. We have had a number of suggestions from our customers and within our team to improve the bird tagging interface. This is to protect the privacy of those who might be near the bird recorders. We are about to start testing an optional feature that will automatically delete any recordings that have human voices. We are actively working on future improvements. ![]() However it can mean there are a lot of boxes on some recordings, like the one below. This may make the tagging process easier because you don't have to draw boxes. ![]() Automatic boxesĪ new algorithm automatically draws boxes around each sound that is identified. Any mistakes that you do see, please just correct the classification and that will help us further improve the models. This means you will expect to see classification mistakes. We are not sure how well it will work because for some of these birds we don't have a lot of data to train and test. Thanks also to Giampaolo (GP) who has taken all of this data and created these models. Thank you to everyone who has helped here. There have also been many calls tagged by the Sumner Bays group and the Extended Wildside on Banks Peninsula. With a little bit of trans Tasman rivalry, the Norfolk Island taggers have done a fantastic job, tagging almost 20,000 calls. Special thanks to those that have been listening to the audio recordings. This is in addition to the birds/sounds we could already recognise noise:this is a generic sound that isn't a bird or some other sound that we're trying to recognise.Thanks to those that have been listening to recordings and tagging birds we can now automatically recognise: We are actively working on some other improvements. We also automatically create boxes around the sounds that we are identifying. We've just rolled out a couple of changes to our bird sound processing that now recognises 18 new birds and other sounds. ![]()
