Sunday Bird Research Survey

     Today we took part in some long term biological research being done by the CEDO research team here in Mexico. We supported the researchers by taking data of the Least Tern nests, eggs, other species, and birds found while we walked in lines down the sandy shore of the Morua Estuary. The Least Terns nests are fragile since they are such small birds so their nests are easily ruined by things like ATV's, human activity, carnivores such as coyotes, as well as loud noises disturbing them.

    Here is a picture of a baby least tern trying to find its balance

The adult Least Tern's have yellow bills and a black and white head pattern.

The researchers need everyone's help in making sure these endangered species stay safe by staying away from the nesting areas and respecting wildlife.

Some fun facts about these beautiful birds are:

  • The male birds offer fish to the females in hopes of mating
  • They are monogamous animals that mate in colonies of up to 25 pairs
  • Their diet consists of squid and schooling fish and they plunge to catch these creatures
  • They only produce 1-4 eggs a season
Least terns migrate from South America between April-June up to the northern Gulf of California to start mating. Baby chicks hatch after 21 days and are taken care of by the parents for around three weeks while they get their "footing". Their nests are very hard to see as I experienced when searching the sand for a small indent created from them sitting and nesting.

Some cool intertidal organisms

Image
  This decorater crab was wearing a hat! (made of sponge) This octopus inked so many times!     In the intertidal zone, we observed many different species. For example, one creature was the o ctopus; part of the Mollusk phylum. We observed the octopus use an ink spray as a form of self-defense in order to deter predators. We saw the organism ink several times in an attempt to scare us away. We also observed the 8 tentacles that are used by this organism to swim, hold things, and get around on land. This was the first of many octopi we would see!     We also saw a strange occurrence of a decorator crab using a chunk of sponge as a protective shell. It seems that the protective sponge also acts as a sort of camouflage in its environment, and helps to keep it safe from predators. These crabs are of the anthropoda phylum and must molt in order to grow. They also have 6 legs. In the second image, we observed a swimming crab. These  crabs are characterized by the...

We made it to CEDO!

Image
  We arrived in Puerto Penasco early this afternoon and got settled at CEDO. The CEDO staff introduced us to the facilities and are very gracious hosts. We are looking forward to a great week!  We had a few minutes to explore the intertidal area before dinner. We saw several species of fish, as well as numerous types of invertebrates, including a sea hare.  We’ll be up early tomorrow to do some intertidal surveys along the beach just a couple hundred meters from CEDO. -Whitney

kayaking

Kayaking in an estuary can be a fascinating and educational experience. Estuaries are transitional zones where freshwater rivers meet the saltwater of the ocean. They are highly dynamic and productive ecosystems that support a diverse array of plant and animal species. One of the most striking features of estuaries is the tidal cycle, which is caused by the gravitational pull of the moon and the sun. Tides occur as the water level rises and falls in response to these gravitational forces. During high tide, water from the ocean flows into the estuary, flooding the area and creating a brackish environment where freshwater mixes with seawater. This influx of water brings in nutrients and sediments from the ocean, which are essential for the productivity of the estuarine ecosystem. As you experienced during your kayaking trip, the movement of the tide can be quite dramatic. The transition from high tide to low tide can happen relatively quickly, and the change in water level can be signifi...
