Sorry, I meant I have 1000 images of each of the 33 species resulting in 33,000 images. I thought that was plenty as I ran a similar bird identification model using the following Kaggle 270 species 1 dataset and received an validation accuracy of 94%.
So I looked over that data and the difference between mine was each of those images were of single bird species whereas mine were from a distance, more than one bird in each image etc.
Thanks, I’ll go through that tutorial and see if there is much improvement.
