MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal
Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation.

Turbine shutdown as an essential tool to prevent soaring bird fatalities at the Gulf of Suez
Climate change caused by high emissions of greenhouse gases to the atmosphere demands for worldwide reduction in
fossil fuel energy production and increased use of wind energy as a clean alternative. However, there is a potential conflict
between wildlife conservation and wind energy production. Bird mortalities may be high at windfarms installed along
migratory flyways and bottlenecks, where a large number of species and large proportions of their global populations
congregate during migration.
The Rift Valley/Red Sea (RV-RS) flyway is the second most important flyway in the world for soaring birds, connecting the
species’ breeding grounds in Eurasia and the wintering grounds in sub-Saharan Africa. Soaring birds depend on thermals
for migration and thus congregate in large numbers at straits and land bridges to avoid long crosses over sea. The Gabel
el Zayt in Egypt, classified as an important bird area is an integral part of the RV-RS flyway. It is located on the shores of
the Red Sea, south of the Gulf of Suez land bridge, and its geographical configuration funnels the migratory birds through
a narrow land strip framed by the Red Sea mountains and the coastline. Wind regimens in Gabel el Zayt are among the
best for wind energy production and large windfarms are already operating in the area.
To mitigate soaring bird mortalities at the 240 MW Gabel el Zayt windfarm, STRIX conducted radar assisted wind turbine
shutdowns during spring migration from 2016 to 2020.
STRIX also established a monitoring program to quantify the number of soaring birds migrating daily, further assess the
international importance of the site, and evaluate the risk of mortality due to collisions. Fieldwork was conducted daily
from early morning to late afternoon at vantage points located at the perimeter and centre of the windfarm. Observers
followed all movements of birds within and outside the windfarm and recorded, among other data, time of observation,
species, number of individuals, flight height and flight direction. Meteorological data was recorded hourly. Daily estimates
of the number of migratory birds were produced by excluding movements recorded by more than one vantage point.
STRIX’s monitoring of soaring birds in the Gabel el Zayt windfarm is to date the most comprehensive study in the region
covering the entire spring migration.
Forty soaring bird species were recorded between 2016 and 2020, including seven globally threatened and two near
threatened species. The total number of soaring birds per year averaged 309,041 individuals and was highest in 2016
with 397,076 recorded soaring birds. Results also show that the site is of international importance for the conservation of
18 species, with numbers recorded per year surpassing 1% of the estimated flyway population. Noteworthy, numbers
recorded for seven species surpassed 10% of the flyway population. Furthermore, the application of migrant collision risk
Band models to evaluate the species’ vulnerability to mortality by collision, indicates that expected mortalities are not
negligible for a large array of species, thus highlighting the importance of conducting radar assisted shutdown operations
at windfarms in the region.

Transitioning our energy economy away from fossil fuel dependence towards one based on renewable and alternative forms of energy requires novel solutions for energy storage, in which the role of hydrogen has promising potential. Very large wind power projects are an increasingly used as source of renewable energy to feed the energy intensive plants for producing green hydrogen and derived fuels, such as green ammonia. But there are concerns of their potential effects on wildlife, particularly on birds. As part of the Total Eren H2 Magallanes Complex, the 10000 MW H2M wind farm is the world’s largest onshore wind power project covering 73.785 ha of Chilean Patagonian grasslands and is included in the IBA (Important Bird Area) of Estancia San Gregorio and in the EBA (Endemic Bird Area) 062 – Southern Patagonia, in the Magellan region of southern Chile, home to the main breeding grounds for the Ruddy-headed Goose Chloephaga rubidiceps, a species classified as Endangered. To address this issue, a comprehensive quantitative radar study was devised to assess the bird collision risk of the Phase 1 (5 GW) of H2M wind power project with focus on the species Ruddy-headed Goose and to design appropriate mitigation actions. The study was conducted over a 12 months period and will provide a detailed understanding of how these species interact with wind turbines. A dual setup comprising of a X-band Birdtrack radar operating in scanning/surveillance and counting modes (horizontal and vertical radar operation, respectively) was used to measure the flight patterns of birds in the study area. This technological approach focused on acquiring empirical and high resolution data for collision risk modelling, including in situ system calibration with bird observers. The use of Birdtrack radar system aimd to increase the accuracy and reliability of the data collected, allowing for a more comprehensive assessment of the behavioural responses of the target species. To calculate species specific risk of collision metrics the model parameters were obtained from x-band radar measured empirical data such as flight height, flight speed, flight direction, mean traffic rates and population densities at two vertical mode ranges (0,4 km and 1,5km) and on horizontal mode range (4,5 km). The methodology used to estimate the collision risks and analyse behavioural responses will provide important insights into species-specific responses and behaviour of the target species at the wind farm to inform appropriate mitigation actions.

Contrasting trends in two Black-tailed Godwit populations:a review of causes and recommendations
In recent decades, the West European population of Black-tailed Godwits, Limosa limosa limosa, has declined in size at a quite alarming rate, while the Icelandic population, L. l. islandica, has undergone a rapid increase in population size. These two populations have been the subject of a great deal of research, much of which has been focused on understanding the causes and consequences of the contrasting population trends. In 2007, a workshop was held during the annual conference of the International Wader Study Group at La Rochelle, France, with the aims of identifying the likely causes of the population changes and providing recommendations for future actions to improve the conservation of both populations. The available evidence strongly suggests that changes in productivity as a consequence of agricultural intensification are the most likely driver of the decline in L. l. limosa, although the concentration of much of the population in just a few sites in winter and spring is likely to exacerbate their vulnerability to future habitat changes. Agricultural and climatic changes are implicated in the expansion of L. l. islandica, and the availability of both intertidal mudflats and wet grasslands as foraging habitats appears to be very important across much of the winter range of this population. A series of recommendations for actions to conserve both populations are provided, including improving agricultural land management and protecting key passage and winter sites and habitats
