5/6 #ISTC20 #Sesh6
The Tagus sites most affected by aircraft noise are those most important to network.

If birds avoid them, netwk has fewer links between sites & higher cost of movemt across netwk. This may impact population's ability to respond to changing envmtl conditions.

(1/1) Hi everyone! I am an undergraduate student and researcher at UCF, and today I will be presenting on how climate change may be differentially affecting the migratory phenology of gray catbirds #BOUsci20 #SESH6 #ornithology

4 #ISTC20 #Sesh6 Nocturnally foraging redshank step less than during the day and use sweeps – a tactile method rarely observed during the daytime sample periods. However, high levels of artificial light partially reverse these effects.

4 #BOU2022 #Sesh6 We previously found a strong influence of breeding propensity on population growth (in prep.), but precise estimates become less important when also quantifying the survival cost of breeding – by estimating excess mortality incurred during the breeding season

6. We conclude that in a warming Arctic, a phenological mismatch drives slower growth in Red Knots. #ISTC20 #BOUsci20 #Sesh6 #ornithology

Number 14 is scary!! 🏝️😱

(5/6) We experience human-kittiwake co-existence is not easy. Urbanization leads to stress to both birds and humans. Strong need for positive solutions (kittiwake hotels and less conflict zones) and overall plans from management authorities. #BOUasm21 #sesh6

5/6 #BOUasm22 This highlights a critical difference between native and invasive species along the same urban gradients whilst highlighting potential drivers of change between the species, including resources, competition, and predation!

5 #BOU2022 #Sesh6 We then created a life cycle with a ‘refreshed breeder’ stage (for the time-step following non-breeding): transitions in/out of this stage can strongly influence population growth, mostly due to the possibility of differential survival of refreshed breeders

6 #BOU2022 #Sesh6 These results indicate a need for data on breeding propensity, mortality incurred during breeding, and vital rates (especially survival) of individuals returning to breeding following a break – with potential from the field and existing individual-based datasets

5. We modelled chick growth and found slower growth for individual chicks that hatched later after snowmelt, as well as in years with earlier snowmelt. #BOUsci20 #Sesh6 #ornithology

(4/6) GPS tracking indicate a change in foraging strategy towards fjords and river deltas. Long foraging duration (31 hr) and distance (410 km) to shelf areas indicate too high costs. Perhaps urban kittiwakes have found new foraging niches in fjords? #BOUasm21 #sesh6

4 #BOUasm21 #Sesh6 | Gulls’ behaviour reflects the balance between perceived risk and reward of a given situation. The behaviour as well as the circumstances in which the behaviour was expressed is logged by the Gulls Eye App

6 #ISTC20 #Sesh6 Results suggest redshank foraging strategies vary significantly with light, both day-night, and level of artificial light. Foraging is more tactile in the dark but high levels of artificial light partially reverse this, with implications for efficiency.

6 #BOUasm21 #Sesh6 | By integrating both sides, the perception of humans and of gulls at the scale of individuals, we can learn about the ‘personalized ecology’ of human-gull interactions

What a fab, thought-provoking session.

The Biden Admin put an end to the federal Covid-19 vaccine mandate on May 11, signaling the end of the pandemic. But NCLA's new video exposes a troubling reality: California's AB 2098 still punishes doctors for advising their patients against the vaccine. youtube.com/watch?v=QRTmhE…

3/4 #BOUASM21 #sesh6 We've shown that fulmars are drawn to heavily fished areas. This affinity with fishing vessels and fisheries introduces a clear source of conflict, as fulmars are the most heavily bycaught seabird species in the North Atlantic.

5 #ISTC20 #Sesh6 Use of probes also increases with light, with them used less at night, unless under high artificial light. Peck rates varied between sites during the day but not between sites at night.
