Which outcome resulted from Aztec chinampa construction limiting aquatic foraging grounds?

When chinampas were constructed, wetland area converted to agricultural land reducing habitat, which limited food and breeding sites for migratory birds, declining their populations. Therefore decreased bird populations resulted, rather than increased disease, salinity or expanded fish farming which have other causative factors.
