I'm not sure he completely undermines himself. Yes, we are definitely growing more birds for food and he could have made that relationship more clear, but at the same time, there is simultaneously a bird "extinction" event going on that also results in an increase in the percentage of birds that are for poultry use.
I'm not sure if you've seen this, but based on an extensive report examining 140 million records of birds, the Oct 2019 paper in Science, "Decline of the North American Avifauna"[0] determined that there are now 3 billion fewer birds in the US since the 1970s:
>"Using multiple and independent monitoring networks, we report population losses across much of the North American avifauna over 48 years, including once-common species and from most biomes. Integration of range-wide population trajectories and size estimates indicates a net loss approaching 3 billion birds, or 29% of 1970 abundance. A continent-wide weather radar network also reveals a similarly steep decline in biomass passage of migrating birds over a recent 10-year period. This loss of bird abundance signals an urgent need to address threats to avert future avifaunal collapse and associated loss of ecosystem integrity, function, and services.
This paper also spurred some articles that discuss the issue such as "Birds are Vanishing From North America" in the NYT [1] and "The Quiet Disappearance of Birds in North America [2]
Then a week after that paper came out, the Audubon Society released a report "Survival by Degrees" [3][4][5] saying 2/3rd of birds are at risk of extinction from climate change alone if global warming hits 5.4 deg F by 2100.
So while the author could have been more clear, the fact is, the evidence is clear that bird populations are rapidly declining due to climate change and the latest reports warn that we must take steps to "avert future avifaunal collapse."
