The morning marshbird survey starts early, 30 minutes before sunrise, which meant Erik Johnson and I were in the boat and at the first survey point by 5:30. The sun didn’t come up until our second point.
We finished up mid-morning and returned to the house.
After lunch, I left Timmy and Erik at the house to take pictures of the study site since I knew I wouldn’t have time when LSU was here tomorrow. Water level was 5 inches below marsh level, and Cells 4 and 5 were well exposed and full of mud cracks. I paddled out to the marsh island landing between Cell 4 and 2, and walked around the east side of Cell 4 and around the north perimeter of Cell 5. I’ll let the photos speak for themselves:

Figure 15. View to the south along containment 5b, with Cell 5 to the left and Cell 4 to the right. The reed containment is stabile enough to serve as a walkway now. This was 10-12 inches of water before we filled it.
Figure 16. View is to the north-northwest from Cell 5 across containment 5a to Cell 3 and the dock beyond. We used this cut to bring the canoe into Cell 5 when we started. It has almost closed up with marsh.

I had brought some supplies for the dredge, so went aboard to do check over the fittings. Once again, the boat-tailed grackles had started a colony within the traveling part of our overhead beam. If they built anywhere else, I would welcome their presence, but the dredge needs this area clear to operate. I had to remove the two nests, one of which already had eggs. I’m glad they aren’t a species of concern! One of the nests even had some of our discarded bailing twine woven into it.
Erik and I had another evening survey to conduct, so I made early preparations for supper, then headed out in the Avocet around 5:00 to mark trails and get underway. We finished up just after sunset and made it back to the headquarters before it got completely dark. I made a modified crawfish etouffee for our supper.
