Field notes #2 Pilot Survey number 2

Summary of second test survey: 

Sigh. Sometimes field work can be frustrating. We were on Holiday break , but decided to go out on the weekend to test out our new wading theory [to get a full count of species behind the mangrove islands in the study area].

Tide tables checked. Time confirmed. Meet at the study site....NOT LOW TIDE. Tip of the day. Don't believe everything you read on the internet!! Our tide table schedule was off about 1.5 hours, so there was no low tide.

The survey was cancelled. We did remain on site and enjoy the pelicans and osprey feeding and the tremendous amount of bait in the area. We did see one Great Egret (Ardea alba) foraging along the mangrove tree island.

So back to the lab we went and redid all the tide charts using NOAA/NOS/CO-OPS tide predictions. Hopefully those will be accurate.

We have adjusted our survey times to one hour before actual low tide, in case the charts are off. Staff are awaiting the arrival of their hip waders so we don't get too icky in the mud flats.

Our official designated start to the project begins Jan 8. So stay tuned. In the mean time, enjoy the photo of a pelican!

New wading bird study

Seabird Study: Utilization of Estuarine and intertidal habitats at the John D. MacArthur State Park

Principal investigator: Diane Arrieta, MSc. 

Research Assistant: Leah Plocharczyk, MA

State permit #11171515

Internships available for Wilkes Honors students (approved by the honors college)

Spring semester internship is already full

This long term study plans to investigate the use of Estuarine and Intertidal Habitats by wading birds at low tide within park boundaries of the John D. MacArthur State Park, located in Riviera Beach, FL [Palm Beach County, FL]. The scheme aims to monitor, assess and regularly update information on the relative importance of inter-tidal feeding areas within park boundaries to document abundance and distribution patterns for the following species.

Species:

*Arrived in Florida VIA natural range expansion.

The objectives of our monitoring include:

1. Assess baseline seabird foraging rates at our four sites

2. Assess seabird roost utilization at sites

3. Assess distribution fluctuations between seasons and environmental conditions

4. Assess baseline levels of human-caused disturbance; especially in Lake Worth Cove
