Utah's Inland Sea Shorebird Reserve

This week is the annual summer outdoor retail trade show in Salt Lake City. I am speaking (on behalf of National Audubon) this afternoon on a panel discussing birding. What else should we panelists do than go birding before hand? Local Audubon staff arranged for a trip out to the Inland Sea Shorebird Reserve last evening, and we were able to spend a couple of hours touring this fascinating wetland.

The reserve is a constructed wetland, one developed by
Kennicott Copper as required mitigation for a mine expansion (see their website for the entire story). According to Kennicott, "KUC actively worked with the Utah Division of Wildlife Resources, the US Fish and Wildlife Services, the Environmental Protection Agency, the Nature Conservancy, the National Audubon Society and the Corps of Engineers on developing the site which was opened in 1997."

We arrived at the wetlands in the late afternoon, long after the grassland birds had quieted for the day. However, on the drive in we did see numbers of typical western scrub and grassland birds such as Sage Thrasher, Lark Sparrow, and Brewer's Sparrow (while exiting we added Northern Harrier and Golden Eagle).

The highlight of our trip was the wetlands that characterize the sanctuary. Snowy Plovers breed prolifically in this area, and among the many that we saw were three downy young. Black-necked Stilt, White-faced Ibis, Canada Goose, and several species of waterfowl (Northern Pintail, Cinnamon Teal, Gadwall) were common in the ponds and pools. Red-winged and Yellow-headed Blackbirds rustled through the reeds. As evening approached several migrant flocks of Franklin's Gulls moved in, stopping before continuing their flights south to their wintering grounds off of the Pacific coast of South America.

I must confess that I am skeptical about the value of many of the mitigation wetlands that I have seen (my preference is to avoid). Yet, in this case, Kennicott and its partners have achieved a success where many have failed. This success has been recognized by Audubon designating the reserve an IBA. I would hope that others involved in mitigation would look to this project as a model of what can be accomplished with thought, planning, sensitivity, and, of course, funding. For more information, read this interesting case study of the reserve by the World Business Council for Sustainable Development.

Particular (and heartfelt) thanks go to the Great Salt Lake Audubon Society chapter for guiding the field trip. I have been associated with Audubon for most of my life, and nothing gives me greater pleasure than meeting a new chapter.

Caribbean Caper and the Barbuda Warbler

I have just returned after spending a week in Antigua and Barbuda, attending the Society for the Study and Conservation of Caribbean Birds conference. I had been invited to give the keynote address, and simply could not say no to another opportunity to meet with the various bird conservation interests in the Caribbean. I had last met with the group in Tobago in 2004, and I wanted to reacquaint myself with old friends and the important work they are engaged in across the Caribbean islands.

Before the conference, though, a number of us took the short flight across to Barbuda. Antigua has a population of around 70,000, and has a well-developed tourism industry (more on that later on the Fermata blog). Barbuda, however, has a small population of around 1500, and a fascinating communal society. Barbuda remains, thankfully, largely undeveloped.

The history of these islands simply repeats a pattern of colonization characteristic of the region (of much of the world, in truth). According to the U.S. State Department,

Christopher Columbus landed on the islands in 1493, naming the larger one "Santa Maria de la Antigua." The English colonized the islands in 1632. Sir Christopher Codrington established the first large sugar estate in Antigua in 1674, and leased Barbuda to raise provisions for his plantations. Barbuda's only town is named after him. Codrington and others brought slaves from Africa's west coast to work the plantations.

Antiguan slaves were emancipated in 1834, but remained economically dependent on the plantation owners. Economic opportunities for the new freedmen were limited by a lack of surplus farming land, no access to credit, and an economy built on agriculture rather than manufacturing. Poor labor conditions persisted until 1939, which saw the birth of the trade union movement in Antigua and Barbuda.

The name Codrington reappears in the lagoon which takes up much of the west of the island. The lagoon is shallow and is bordered by extensive mangrove forests. The most extensive Magnficant Frigatebird breeding colony in the world is located on Man of War Island, situated north of Codrington (the main settlement on the island) bordering the lagoon.

During our trip we visited the frigatebird colony. The males had yet to return to nest, and most of the remaining birds were juveniles and females. Yet by boat we were able to see hundreds of these spectacular birds, many within arm's reach. There were Brown Boobies roosting within the colony as well, and we heard and saw several of the local breeding Yellow Warblers (these of the "golden" warbler or Petechia group).
Speaking of warblers, the next part of our trip focused on the endemic Barbuda Warbler (Dendroica subita). In 2000 the American Ornithologist’s Union (AOU) ’split’ D. a. adelaidae into three monotyoic taxa under the names Adelaide’s Warbler D. adelaidae (endemic to Puerto Rico and Vieques), Barbuda Warbler D. subita (endemic to Antigua and Barbuda), and St Lucia Warbler D. delicata (endemic to St. Lucia). This warbler is found in the thorn-scrub on the western third of the island. During our time there we had no difficulty finding the bird, and by trip's end we had seen easily a dozen. Additional birds of interest found in the Barbuda forests were Lesser Antillean Flycatcher, numerous Caribbean Elaenias and Black-whiskered Vireos, and Gray Kingbirds at virtually every stop.

I find these isolated populations of parulids to be among the most fascinating birds. Most of us are exposed to the genus Dendroica through the wood warblers that breed and migrate through the Americas. Many of these birds are long-distance migrants, and only stop briefly in my yard in Galveston to feed and rest before continuing either to the tropics or back to their breeding grounds in the northern forests.

But here, on Barbuda, there is an isolated, non-migratory species of the same genus that exists no where else in the world. Birdlife International estimates a total population of 1500-2000 on Barbuda. With sea level rise associated with global climate change, it is not hard to see how such an isolated species is a grave risk. Barbuda, unlike Antigua (with Boggy Peak, soon to be Mount Obama, over 1300 feet high), the highest point on Barbuda is only 100 feet.

The other (and most immediate) threat to both islands (in fact to the Caribbean as a whole) is unsustainable tourism. Resorts and cruise ship terminals continue to spread through the region, although Barbuda still remains largely undeveloped. I can only hope that Antigua and Barbuda, after the latest financial fiasco, will consider a more sustainable form of economic development, one that respects the environment and is inclusive of the local residents.

Thanks to Mike Pienkowski, who accompanied us on the field trip, for allowing me to use a couple of his photos of the Barbuda Warbler. These were taken during our field trip.

Let There Be Ducks

The preliminary estimate of total ducks from the 2009 Waterfowl Breeding Population and Habitat Survey was 42 million, which is 13 percent greater than last year’s estimate and 25 percent greater than the 1955-2008 average.

The entire report is available on the USFWS Migratory Bird website.
