I met Dr. Eduardo Corona at a latest College of Texas City Hen Venture presentation in San Antonio, Texas. Corona shared his work on “Birds and their biocultural position in Mesoamerica.” Dr. Corona is an archeologist and researcher on the Instituto Nacional de Antropologia e Historia (INAH) in Mexico and a distinguished member of Mexico’s Nationwide System of Researchers.
Dr. Corona’s analysis on Hen use in Central Mesoamerica, studies that “biocultural components come from people interacting with biodiversity by way of tradition and language. They embrace information concerning the pure surroundings, in addition to social and cultural norms that individuals and cultures generate and settle for as their rights and tasks.”
Having noticed and documented nesting Migratory Egrets and Herons in San Antonio for the final six years, I perceive the position that we every play within the conservation of those migrant birds, their habitats, and the connections that we share between our countries-Mexico and the US of America. Mexico and the US should not the one international locations we now have facilitated “agreements” with for the safety of migratory birds.
Traversing a continent to maintain their species alive is not any small feat for our migratory birds that we share intercontinentally. In accordance with Britannica.com this implies “referring to or touring between continents.” Migration is the seasonal motion from one area to a different, typically from North to South to seek out one of the best ecological situations and habitats for feeding, breeding, and elevating their offspring. Important to the birds are the wetland habitats wanted to breed comparable to these in San Antonio.
Are we doing sufficient to guard the birds? The Migratory Hen Treaty Act (MBTA) of 1918 carried out 4 worldwide conservation treaties that the US entered with Canada in 1916, Mexico in 1936, Japan in 1972 and Russia in 1976. The MBTA is meant to make sure the sustainability of populations of all protected migratory hen species.
Government Order 13186: Tasks of Federal Businesses to Defend Migratory Birds: Migratory birds are of nice ecological and financial worth to this nation and to different international locations. They contribute to organic range and convey super enjoyment to hundreds of thousands of People who research, watch, feed, or hunt these birds all through the US and different international locations.
The Ramsar Conference got here into pressure in 1975 with virtually 90% of United Nation Member States, a few of the worlds geographic areas turning into “Contracting Events,” together with the US in 1986. The Conference acknowledges that “Wetlands are among the many world’s best environments; cradles of organic range that present the water and productiveness upon which numerous species of vegetation and animals rely for survival.” The significance of wetlands | The Conference on Wetlands, The Conference on Wetlands (ramsar.org)
Canada, Mexico, and the U.S. share a big selection of ecosystems, habitats, and species, linked by sturdy financial, social, and cultural ties, in line with the Trilateral Committee. “To extra successfully handle priorities of continental significance and increase the concerted efforts of the three international locations of the North America bioregion, the Canada/Mexico/U.S. Trilateral Committee of Wildlife and Ecosystem Conservation and Administration was established in 1995.” Trilateral Committee for Wildlife and Ecosystem Conservation and Administration
With Government Orders, Treaties and Committees created to guard our migratory birds, why can we proceed to permit the destruction of habitat? Why can we proceed to permit the destruction of nests with viable embryos and the deadly take of grownup birds by the USDA Wildlife Providers?
The Fish & Wildlife Service points quite a few Depredation permits yearly that enable for the deadly take of Migratory Birds. The permits issued to the USDA’s Wildlife Providers “contracted to handle” wildlife deemed a “nuisance or well being hazard” can lead to the killing of hundreds of thousands of animals per yr.
Why do they return? Analysis means that Yellow-Topped Night time-Herons typically use the identical nesting websites for a number of years in a row. This has been documented, suggesting this species does exhibit nesting website constancy in line with spanishbirdguides.com.

How far do they journey? The Yellow-Topped Night time-Herons are medium to lengthy distance migrants in line with allaboutbirds.org, with Gulf Coast populations shifting throughout the Gulf of Mexico or alongside the coast to Central and South America.
A Yellow-Topped Night time-Heron flying at round 20 miles per hour-traveling from the Gulf of Mexico shoreline to San Antonio, touring 200 hundred plus miles, can take the Heron over 40 days to journey the space between the 2 international locations. Touring from a spot comparable to Veracruz, Mexico, over 700 miles away from San Antonio, it would take the Herons greater than 145 days of journey at 20 mph in line with www.timecalculator.web. The Herons can face drought, scarcity of meals and loss of life throughout migration.
Migratory Barn swallow migrations can cowl many hundreds of miles for an animal that weighs lower than an oz! Flying about 200 miles per day can fluctuate relying on elements comparable to climate, wind, and meals availability. The Swallows can journey as much as 6000 miles on every migration, twice annually, departing within the fall, and returning within the spring. American barn swallows migrate to Central and South America, so far as Argentina.
Their worth: Swallows present us with an ecological service as insect controllers. They notably eat swarming bugs comparable to bees, wasps, flies, damselflies, moths, grasshoppers, crickets, and extra. It’s common for individuals to submit nesting constructions to supply houses for these insect controllers.
Situated within the Central Flyway Zone, we now have many species that spend time all through the area, comparable to Kingfishers that breed so far as northern Alaska and Canada after which migrate south for winter. Belted Kingfishers that winter all through Mexico and Central America to northern Venezuela and Colombia have been noticed in San Antonio.
With all of the analysis on the market and agreements between international locations, worldwide treaties, and committees, we nonetheless face the lack of biodiversity on a monumental scale. If there may be one factor that I discovered from my go to with Dr. Corona is that there’s a possibility for renewed partnerships between our international locations and a possibility to be taught extra about our migratory birds and the intercontinental connections that we share. Work is required for a sustainable future for our migratory birds.
As Dr. Corona’s ends his presentation, He reminds us that, “To guard the birds and all the various organisms, we now have to work each day and contribute.”
It’s time we cease taking a look at Migratory Birds as a “nuisance or inconvenience” and learn the way we are able to be taught to coexist with the birds and different species we share with different international locations. Afterall, it’s a good distance traversing a continent simply to maintain their species alive!
