in the winter. Flycatchers seem to have taken advantage of reduced competition as also great tits noted a30-40% drop in breeding pairs (100 pairs more of the collared flycatcher). Let’s hope it was just a fluctuation and significantly colder winter… last pic - a ringed tree pipit found in our plot;)

The number of breeding BT pairs dropped by 50% (sic! ~90-100 broods fewer!) Many broods are clearly attended by 1 parent, and we’ve noted almost a 100% drop in the number of recruits (1-2% of recruited 2nd yrs instead of the usual 20-30%). Our Swedish friends also reported almost no BTs in feeders

Day 68 of the 47th # Gotland season! After some May showers Gotland returned with dazzling sunny weather :) first flycatchers started to hatch, but this years weird. The blue tit population was hit hard by blåmessjuka („blue tit disease”) caused by Corynebacteria - Suttonella ornithocola.

Are we doing simulations wrong? This paper convinced me we are. doi.org/10.1098/rstb... Usually we run 2 sets of "worlds" w and w-out intervention. Gives large uncertainties that include negative (harm) effects of interventions that are actually always positive (beneficial)!
Figure 5. Time series showing cumulative number of cases averted at each time caused by the intervention calculated using our method (single-world) and a
standard method. Shaded regions denote 90% confidence intervals. Note that there is more variation in the middle of the epidemic, so it may seem as though the
number of cases averted is large during those times. (Online version in colour.)
