“…For example, the preferred nesting substrate may be present at a lower elevation than neighboring sites and subject to increased risk of flooding (Rounds et al, 2004). Or for marsh-nesting terns, flooded fields may attract terns to nest, but result in breeding failure when the fields dry up (Paillisson et al, 2006). Such a mismatch between habitat selection cues and fitness is most likely in locations where traditional colony sites have been lost or the nesting habitat has recently undergone rapid change (Cook-Haley and Millenbah, 2002;Battin, 2004;Rounds et al, 2004;Sih, 2013).…”

Managers must therefore ensure that habitat manipulation does not simply attract terns to nest, but also improves nest success (Cook-Haley and Millenbah, 2002;Paillisson et al, 2006).…”

Behavioral research has long had an important role in the conservation of terns (Aves: Sternidae). Habitat management and restoration of breeding colony sites depends on knowledge of the cues used to select colony and nest sites. For example, conspecific attraction with playback and decoys is commonly used to bring terns to suitable colony sites and habitat modification is often used to increase the availability of suitable nest sites. Tern colonies are interconnected by dispersal, and a metapopulation approach is needed for effective management. Population dynamics are therefore affected by behaviors that influence the frequency of movement among colony sites: site fidelity, natal and breeding dispersal, and group adherence. The monogamous breeding system of terns should keep effective population size similar to census population size, but variation in sex ratios (likely resulting from sex differences in behavior) and in parental quality can result in a smaller than expected effective population size. In addition to the behavior of terns, knowledge of the behavior of predators on terns contributes to management plans, because predator behavior can sometimes be manipulated and predation is often performed by only a few specialized individuals. Other examples of links between tern behavior and conservation are also briefly reviewed, such as behavioral toxicology research and studies of behavioral responses to human disturbance and manmade structures. More work is needed on the behavior of migratory terns at staging sites, stopover sites and wintering grounds, and on the behavior of less well-studied species and species in less well-studied geographic regions [Current Zoology 60 (4): 500-514, 2014].

“…In time, the water soldier patches become denser and more resistant to sinking under the weight of the birds. In the case of the third member of the genus-Whiskered Tern Chlidonias hybrida-a strong association was demonstrated between vegetation growth stage and clutch initiation date (Paillisson et al 2006). In the case of CHL, the statistical significance of the variable describing colony location (colony identity) indicates that these factors affect the colony as a whole.…”

Wind differentiates reproduction in the non-expansive Black Tern Chlidonias niger and the expansive White-winged Tern Chlidonias leucopterus

Identifying the key factors governing the expansion of a species' range is difficult because of the multiple interactions of environmental and biological factors. Among the biological factors are breeding parameters, which at the edge of a species' range may indicate the traits involved in limiting species distribution. To evaluate whether the hatching success of two sympatric species of terns was dependent on weather parameters, a study was carried out in the valley of the River Bug in eastern Poland. During 2007-2010, nine colonies with 113 clutches of Whitewinged Tern (CHL, an expansive species, new to the region since 1997) and 92 clutches of Black Tern (CHN, a non-expansive species, nesting in stable numbers in this region for many years) were monitored. CHN arrived on average 9 days earlier than CHL. While CHN arrived in east-central Poland earlier and earlier during the 1998-2013 period, no such trend was recorded for CHL. The clutch initiation median in CHL was 8 days later than in CHN. The hatching success of CHL was statistically less than that of CHN (41.6 vs. 69.6%). A general discriminant analysis model showed that successful CHL clutches depended on the maximum daytime wind speed (strong winds can be disastrous for breeding terns), colony identity and clutch initiation date. In the case of CHN, none of these factors had a statistically significant influence on hatching success, although the clutch initiation date was very close to being significant. These results suggest that a species which nested in the same location for a long time in relation to ambient weather conditions has higher hatching success than the one which is in the process of expanding its distribution range.

“…During the first or second inspection of the colony, habitat parameters were measured where nests had been built. These parameters were chosen on the basis of papers dealing with habitat selection in Chlidonias terns (Paillisson et al, 2006;Maxson et al, 2007). They were as follows: (1) water depth to the hard bottom (cm); (2) distance of the nest from the wall of helophytes (m); (3) coverage of floating vegetation (mainly Water Soldier) within a 2-m radius of the nest (%); (4) coverage of helophytes (mainly sweet flag and rushes) within a 2-m radius of the nest (%); (5) height of vegetation above water level within a 0.2-m radius of the nest-mean of four measurements made in the principal compass directions (cm).…”

Nests should be built on sites that provide optimal conditions for reproduction, so nest site characteristics are assumed to have an adaptive value. In this paper, we compared the hatching success of two species of terns: Black Tern (Chlidonias niger) (a nonexpanding species) and White-winged Tern (Chlidonias leucopterus) (an expanding species, new to the region since 1997) with respect to microhabitat nest characteristics on oxbow lakes in eastern Poland. The hatching success of White-winged Tern was lower than that of Black Tern (41.7 vs. 66.7%). Comparison of habitat parameters at the nesting sites between the two tern species showed a significantly greater depth of water and distance from helophytes in Whitewinged Tern. Successfully hatched White-winged Tern clutches were situated much closer to the helophytes and were initiated on average up to 8 days earlier than clutches that failed to hatch. In Black Tern, hatching success was not influenced by environmental factors describing nest location. In eastern Poland, oxbow lakes are probably a suboptimal habitat and constitute an ''ecological trap'' for White-winged Tern; because of these suboptimal habitats, the expansion of this species may be quite slow in predominantly dry years in eastern Poland.
