Yes, this observation is testable because you can do the experiment with your own controlled conditions and see if this with the milk would happen again.
It is qualitative observation because you use your senses such as sight, smell, touch, taste or hear to observe the results (in quantitative observations you use instruments for measurement).
Null hypothesis: The taste of the milk is the same when it is left on the counter (warm) and when it is left in the refrigerator (cold) or simply saying the place where we put milk doesn’t affect the milk taste
Hypothesis: The milk left on the counter is sour due to acidification of milk via bacteria that works on warmer place.
Independent variable (changed by a scientist in order to affect the dependent one) is a place where we put milk (temperature).
Dependent variable is milk (milk taste).

Based on this information it can be said that this formation between the islands and the mainlands will most likely cause an increase in gene flow between the bird populations. Since the islands and the mainland are now connected birds from both these two different habitats will begin mating and producing progeny, thus causing gene flow to increase between these species.
