As April passes into May, many migratory birds leave the tropics of Central and South America in search of bountiful summer resources in the sub-tropical United States. Among them, the very charismatic Prothonotary Warbler flies from the northern tropics to the hospitable habitats of the United States. Prothonotary warblers live in forests near bodies of slow-moving water where they can hunt for insects and nest in cavities in trees. The cypress swamps of Louisiana are about as good as it gets for a prothonotary warbler, and they stay from April to August.  If you get out into the swamp during the summer, look for their bright yellow figures darting through low-lying foliage.
Prothonotary warblers have experienced a population decline in recent years that experts attributed to the destruction of their wintering habitat in the tropics. To improve breeding success and survivorship, the Audubon Society and other ornithological enthusiasts have encouraged people to install nest boxes that help to protect warbler nests from failing. Many natural threats exist in swamps for warblers, including a variety of snakes, birds of prey, and mammals. Since brown-headed cowbirds will use prothonotary nests to lay their eggs in when given the chance, nest boxes are suggested to have a 1¼“ hole to prevent larger birds from entering the box but still allow the warblers to enter. Boxes are not left on the ground, and are often mounted on poles. Some predators can climb, so many boxes have a skirt/collar that prevents snakes, raccoons, and cats from climbing the poles into the nests. More guidelines for a good nest box can be found at https://nestwatch.org/learn/all-about-birdhouses/features-of-a-good-birdhouse/.

At this time of year in Louisiana, you are sure to see early morning waterfowl hunters dressed in their best camouflage. Louisiana sits on the Mississippi Flyway, North America’s most heavily-used migration corridor for waterfowl. Louisiana’s coastal wetlands provide habitat for more than five million migratory waterfowl, approximately half of the wintering duck population of the Mississippi Flyway. The coastal marshes of Louisiana provide habitat to mottled ducks, wood ducks, redheads, and pintails, just to name a few species. These waterfowl species can be spotted in coastal marshes, flooded timbers, flooded grain fields, and other wetland areas. Grab your waders, shot gun, and a duck call, and take advantage of Louisiana’s Sportsman’s Paradise.
It is critical to protect the coastal marshes and wetlands within the state for Louisiana to remain the front runner for waterfowl hunting. CWPPRA projects are aimed at protecting and restoring Louisiana’s coastal wetlands, ensuring that wildlife and the people who hunt them have the habitat they need.
World Migratory Bird Day was initiated over ten years ago as a way to raise global awareness for the conservation of migratory birds and their habitats. Each year, people around the world organize events, such as bird festivals, exhibitions, and bird-watching excursions to celebrate this day. All activities celebrating World Migratory Bird Day are tied together by a common theme. World Migratory Bird Day 2017 was officially celebrated on Saturday, May 13 with the theme “Their Future is Our Future,” which shed light on the interdependence between people, nature, and migratory animals — particularly birds. The goal of this year’s campaign is to raise awareness of the need for sustainable management of natural resources, including wetlands, demonstrating that bird conservation is crucial for the future of humanity.
Among the wetland attributes society aims to protect and restore are those that benefit wildlife, such as migratory birds. One of the best known functions of wetlands is to provide a habitat for birds to breed, nest, and rear their young. This natural resource is used for drinking water, feeding, shelter, and social interactions. Wetland vegetation provides protection for migratory birds from predators and destructive weather. The presence of an adequate shelter is often crucial to the survival of migratory birds.
The value of a wetland varies for each bird species depending on the amount of surface water, amount of moist soils present, and the duration of flooding. Other factors that commonly affect the value of wetlands to a specific bird species are availability of food and shelter and the presence or absence of predators within the wetland. Availability of water influences whether migratory birds will be present, how the birds will interact with the wetland, and which species will be present. Species of migratory birds may spend the winter months in the Southern United States using the wetlands for food and nutrients to sustain them for their journey north. Many migratory birds are highly dependent on wetlands during the migration and breeding seasons. Habitat loss in breeding areas means population loss for most wetland dependent birds.
Water, promoter of all life forms on Earth, is recognized today- World Water Day! In Louisiana, 47% of the state’s population resides in the coastal zone, with a majority of livelihoods reliant on water. Industries such as aquaculture, agriculture, oil and gas, and tourism depend on the sustainability and quality of Louisiana’s waters. This essential natural resource has a synergistic relationship with Louisiana’s wetlands, providing vital nourishment to fisheries, wildlife, and Louisiana’s coastal growth. Wetlands improve water quality by trapping suspended solids and filtering other pollutants. Coastal marshes filter excess nitrogen and phosphorus, thus helping to prevent algal blooms and maintaining oxygen in the water for fish and shellfish. Wetlands can retain, remove, and transform nutrients that might otherwise contribute to declining water quality. Clean water is important for healthy fish, wildlife, and humans. Water is not only a commodity, but a contributor to life… appreciate it, preserve it, and protect it!
Water is the key to life, celebrate World Water Day!
Known to be one of the most easily recognizable species of waterfowl, the mallard duck is majestic, distinctive, and a wintering resident of the bayou state. The mallard is one of the most common ducks in the United States. With great variation between the two mallard genders, drake or male mallards have a bright yellow bill, prominent emerald green head, and white neck-ring, followed by a chestnut colored chest and dark colored rear. The hen or female mallards have a dark colored bill and are a mottled brown color with a dark brown stripe across the eye. Both drake and hen mallards have the characteristic violet-blue speculum with black and white borders. Mallard ducks are a migrating waterfowl species that can be found in Louisiana during winter. Among the dabbling ducks, mallards are one of the latest fall migrants with one of the most extended migration periods, lasting from late summer to early winter. During their migrant stay, mallards are found in agricultural fields, shallow marshes, oak-dominated forested wetlands, and coastal inlets with aquatic vegetation. Louisiana sits in the Mississippi Flyway, North America’s greatest and most heavily-used migration corridor. Louisiana’s coastal wetlands provide habitat for more than 5 million migratory waterfowl, approximately half of the wintering duck population of the Mississippi Flyway. Now, more than ever, restoration and protection of coastal wetlands is critical; if wetlands continue to diminish, Louisiana will no longer be known as “sportsman’s paradise”.
