We conducted our annual survey for cormorant on June 17th, 2019. We have not finished counting the nests yet. We started monitoring in 2014 and this is the fourth count in five years. The number of nests has remained relatively stable since 2014: 180 (2014), 190 (2016), 179 (2017), 181 (2018). That being said, if each nest produces 3-5 young, there could be close to 1500 cormorants at one time near the end of the summer and luckily, the wetland appears to be able to support a number of fish-eating birds, including herons, pelicans, grebes, eagles and ospreys.
This is a view of the cormorant colony from above. The "guano" from the cormorants seem to be detrimental to the cottonwoods in which this species likes to nest.
