More than 847,000 birds of 26 species have been reported nesting in the area's coastal swamps and marshes, and on barrier islands (Portnoy 1977). For several species, more than half of their entire U.S. coastal population breeds in these states (Spendelow and Patton 1984 ). Clearly this region is important for these birds, and their, nesting sites require protection. Nesting colonies in this area were completely censused by both ground and aerial surveys in 1976 (Portnoy 1977). In 1978, aerial surveys were used to check the status of previously located colonies, and results indicated that 25% of the 1976 sites were deserted (Portnoy 1978 and Table 1 on page 4 of this report). A 1981 survey of a small portion of the area again indicated more deserted colonies (Keller 1981). It seems most probable that these deserted colonies were the result of birds moving to new colony sites, but neither the 1978 or 1981 surveys searched for new colonies. Thus, resource managers were left with insufficient information regarding new colony loca- tions to effectively protect these areas. The present survey was conducted to update the status of previously recorded colony sites and to search the study area for new colonies. Our objectives were to (1) locate and map all active colonies on 1:24,000 and 1:250,000 scale maps, (2) check the status of all historic sites except for Least Tern (Sterna antillarum) sites, (3) determine the species composition of the colon`y_,_(24@ estimate overall colony size, and (5) record habitat(s) used for nesting by the various species. METHODS STUDY AREA The study area includes the coastal marshes, beaches, and barrier islands of Louisiana, Mississippi, and Alabama, and the inland swamp and marshlands of the Atchafalaya Basin, Lake Maurepas and Lake Salvador regions (Figure 1). This is the same area surveyed in 1976 and 1978. Subsidence, accretion, erosion, and delta formation are all active processes in the study area which result in rapid changes in the landscape of the coastal region. We relied heavily on wetland habitat maps constructed from 1978 aerial photography by Coastal Environments, Inc. (Wicker et al. 1980) for the most up-to-date illustration of the landforms. These 1:24,000 scale maps use the wetland classification system designed by Cowardin'et'al. (1979).

If wetland maps were not available at this scale for some inland areas, the most recent U.S. Geological Survey (USGS) topographic maps were used instead. SURVEYS Aerial surveys of the study area were conducted twice during the breeding season. The first set of surveys was conducted using a fixed-wing aircraft ,(Cessna 172) on 7 days from 2 to 17 May. At this time the wading birds (herons, egrets and ibises) and Forster's Terns (Sterna forsteri) were nest- ing, but the gulls, other terns, and Black Skimmers (RyF_c@_opsaLqer) that nest on beach areas had not yet begun. Colony sites located in 1976 and 1978 were surveyed, and additional swamp and marsh areas were intensively searched for new wading bird colonies. The use of fixed-wing aircraft at this time enabled a cost-effective search of the large expanses of marsh and swampland used by nesting wading birds. The second set of surveys was conducted on 6 days from 2 to 14 June using a Bell Jet Ranger helicopter. Colonies discovered in May were surveyed again and beach areas were intensively searched for new colonies of the later- nesting gulls, terns, and skimmers. In June we chose different flight routes to colonies in the marsh and swamp habitats to increase our coverage of the study area. The use of a helicopter during these surveys allowed us a more detailed examination of each colony, and resulted in a more complete assess- ment of species composition and better estimates of colony size. 2 Ninty-one flight hours were logged during the study. Figure 2 illus- trates the flight routes taken during the surveys. Active colonies were usually visible within 1 km of either side of the airplane, but concentrations of feeding adults or flight lines of birds often led us to colonies farther from the plane. Colonies including Great Egrets (Casmerodius albus) could be seen at greater distances than other colonies because these T@_rgewhite birds nest in the tree tops. Colonies of darker birds, such as Tricolored (Egretta tricolor) or Little Blue Herons (L. caerulea) nesting in shrubs were more difficult to locate. White This (Eudocimus albus) colonies, where the birds were nesting in the lower branches or understory shrubs of cypress/tupelo swamp, were also difficult to see from a distance. DATA COLLECTION During surveys, one principal observer (JAS) described species composi- tion, nesting habitat, and also estimated colony sizes. A second observer (CEK) assisted with species observations and estimates of colony size. Colony sizes are estimates of the number of birds visible from the aircraft. (See Table 2 on page 14 for description of size classes.) The second observer also navigated and plotted colonies on USGS 1:250,000 scale maps. A third observer (RDG) plotted colony locations on 1:24,000 scale maps which were either USGS topographic or wetland habitat maps, depending on which were available for the area. Colonies were defined as groups of birds nesting together and separated by at least I km from other groups of nesting birds. Exceptions to this were made when birds inhabited islands which were less than 1 km apart, but the species composition on the two islands was substantially different. For example, a mixed group of herons nesting on one island, and Forster's Terns on another island 0.5 km away, were labeled as two separate colonies. The 1 km- distance was also used to determine if historic sites were deserted. If nesting birds were not found within a 1 km-radius of the historic location, MISSISS LOUISIANA APM 105 Figure 2. Flight routes taken dur-ing surveys. 3 the colony site was considered deserted. Historic locations were determined from Portnoy (1976, 1978), Keller (1981), and site maps drawn by John Portnoy for each colony on data forms on file at the Colonial Bird Register, Cornell Laboratory of Ornithology, Ithaca", New York. Species considered in this report are listed in Table 2 on page 14. Though Least Terns are included, they are too small and cryptic in single- species colonies to always be detected from an aircraft. However, they could be observed after locating a colony also occupied by other birds. For this reason, historic Least Tern colonies are designated with a "0*" to indicate that although no birds were observed, the presence/absence of this species could be adequately assessed from the air. COMPARISON OF 1976, 1978, and 1983 COLONY LOCATIONS Nesting sites of colonial birds tend to be used year after year, but (as illustrated in Figures 4 through 9), some colony sites are deserted. In order to analyze colony stability and colony site desertion, we have chosen 134 colonies that were surveyed in all 3 years (Table 1). This excludes seven Least Tern colonies and any sites not visited in all 3 years. Sixty-seven colonies (50%) were active in all 3 years. Twenty-five colonies (19%) were deserted by 1978, 30 colonies (22%) were deserted by 1983, and 12 colonies (9%) were deserted in 1978 but recolonized by 1983. Table 1. Subsequent attendance of 134 colony sites first observed in 1976. X = active, 0 = deserted. Attendance Number and % of colonies history 1976 1978 1983 with each attendance history Stable x X x 67 (50%) Deserted in 1978 x 0 0 25 (19%) Deserted in 1983 x x 0 30 (22%) Recolonized x 0 x 12 9%) 134 Considering that 102 new colonies were found in 1983, colony desertion is most likely balanced by birds shifting to new colony sites. The reasons for colony site desertion and recolonization are complex and can include habitat changes, flooding, disturbance, predation and competition (McNicholl 1975, Ogden et al. 1979; Erwin et al. 1981; Burger 1982). Disturbance, predation, and competition could not be evaluated in this study, but changes in the coastal habitat are pronounced in Louisiana and were apparent causes for shifts at some sites. For example, eight of the colonies deserted by 1983 were on coastal islands which were either completely or nearly submerged in 4 1983. The unusually high water levels of 1983 no doubt contributed to this probl em. Habitat changes may also create new sites. Birds apparently de- serted colony sites 602010, 602011, and 602012 and shifted south to newly formed islands of the building Atchafalaya delta (colonies 602080, 602081, 602082). Although we cannot confirm this without marked birds, species com- position of the three deserted sites and the three new colonies are similar. The conclusion of this is simply that.' colony 'distributions are changing and at this time we do not know what, if any, effect this shifting has on population numbers. Updates of colony distributions will have to be continued to keep accurate distribution information. The colony turnover rate (Erwin 1977) is 0.14 per year, indicating a 14% change in colony distribution every year (desertion plus establishment). We recommend, therefore, that colony surveys be repeated every 2 years to maintain accurate distribution informa- tion. ATLAS ORGANIZATION The atlas is arranged in three sections. First is an index map (Figure 3) and a series of photographically reduced 1:250,000 scale maps (Figures 4-9) which depict present and historic colony locations. All colony sites are assigned a six-digit number. The first three digits identify the 1:250,000 scale map (Figure 3) where the colony is located, and the last three identify the individual colony. This number system is used in all U.S. Fish a,nd Wild- life Service colony atlases, and colonies identified in 1976 or 1978 retained their same number. Table 2 explains the number and letter codes used in Tables 3 and 4 to describe the status of all colony sites, and the species composition and over- all colony size of active colonies. Table 3 gives the status of all colony sites depicted on the 1:250,000 scale maps',and is arranged numerically by colony numbers so that information regarding a colony located on any map can be easily found. Table 4 describes the size and species composition of all active sites found in 1983. The location of these colonies are depicted in the third and largest section, a series of reduced 1:24,000 scale maps. These are either 1978 wetland habitat maps or USGS topographic maps if wetland habitat maps were unavailable for the area. These maps are arranged alpha- betically by quadrangle name. 5 @,qMjjjjjjjjjjPFF?M _N4, 14,!Tvw ,14 qi@ Aw Immature Great Egrets. Photograph by C.E.
