When Brown Pelican hatch they are small, featherless and helpless. These birds can grow from tiny nestlings to flighted juveniles in 12 weeks.

Melissa Roach, biologist with the Patuxent Bird Banding Lab, bands a pelican chick on Smith Island in the Chesapeake Bay.

Immature oocytes within the testicular tissue of a smallmouth bass.  The histological or cellular appearance of an intersex smallmouth bass. Immature oocytes (white arrows) are present within the testicular tissue which also contains mature sperm (yellow arrows).

Eelgrass (Zostera marina) forms extensive meadows in low intertidal and shallow subtidal areas of estuaries and embayments along the Northwest Atlantic coast. Ranked among the most productive plant communities on the planet, eelgrass beds are noted for contributing valuable ecosystem functions and services to the coastal zone.

Three biologists with the USGS Bird Banding Lab at Patuxent Wildlife Research Center prepare to band pelican chicks on Smith Island in the Chesapeake Bay.

Researchers monitoring frame for marked bees and colony health.  The associated project is Impacts of fossil fuels on pollinators.

Bees tagged to allow researchers to monitoring their foraging behavior.

Associated project title "Impacts of fossil fuel combustion on pollinators"

Bee with tag light blue 84 on comb. Bees tagged so researchers can monitor individual bee foraging behavior. 

Johanna Nifosi uses forceps to sample a flower for eDNA extraction in Indiana Dunes National Park. eDNA will be extracted and sequenced for the detection of pollinators such as bees.

Newest member of the Bird Banding Laboratory has a long history with birds.

Hexagon-based aerial survey design with transects overlaid. The EPA 40 km² hexagons (White et al. 2018) were overlaid across the entirety of the northern Gulf of Mexico. Sampled hexagons were then selected using a Generalized Random Tesselation Stratified (GRTS) sampling scheme.
