  Keeping HOSP out of bluebird boxes?

  I've dealt with keeping larger birds from raiding bluebird boxes, but recently have had issues with HOSP going in and destroying bluebird nests and killing chicks. Any suggestions?

Low light is no issue as a small LED light could be used to focus at this time on the BB as it perches near the entrance hole, like a porch light, the camera need not be a hi fi one but a cheap web cam modified to a much smaller size, which can take an image keep it in a memory and transmit it to a senser, which gives a small current that triggers a magentic response on a liver to open the door. The camera and the light can be placed inside the roof just above the entrance and only work when the bird appears at the porch. Once the image of the nesting pair nesting has been adapted by the sensor for head or body characters-size shape and colour, and allow only these two to enter for a programmed period of time, but not others.The whole system can run powered by battery. Idont know what others just think about it. Good day!

  What are the short-term impacts of deforestation and dam formation on adjacent communities of terrestrial vertebrates, mainly tropical birds?

I am looking for studies/researchers that assessed the effects of deforestation followed by flooding for dam formation on communities living in habitats adjacent to the ones affected. Specifically I adress the following questions: is there evidence on escaping fauna? Do these individuals estabilish at habitats near the supressed ones, or do they make long range displacements? Do escaping individuals interfere with local (not affected) population density? Are these changes also related to modifications in predation rates, territorial defense or individual fitness?

As already stated, there are plenty of variables that can lead to elusive interpretation, but my first approach is to rely on descriptive patterns of the community before the impact event, during the deforestation process, and after the dam has been estabilished. One of the findings is exactly on fugitives. Not all species evade the deforested areas: some are more prone to maintain their original territories for some time, and either leave after the resources are depleted, or are killed by predation or famine. I have also gathered data that indicates that escapees have effects on local bird abundance/density and territory (singing) behavior. However, many classical ecological indexes do not seem to be sensitive to these changes. In any case, it seems that this phenomenon was not thoroughly studied in previous enterprises, is that correct? Are there published reports on this topic (I have been unable to find any)?

    Hi Mark, I've also been told that maggots are good samples for the mice bioassay, but the problem now is where to send these samples (I couldn't find any lab in PT yet). I'll contact EWDA, thanks forHi Mark, I've also been told that maggots are good samples for the mice bioassay, but the problem now is where to send these samples (I couldn't find any lab in PT yet).

    It seems that you are interested in more instantaneous deaths of birds in a large population, if so what I have mentioned here may prove of no use to you. OK good luck with your work.

Steps need to be taken in preserving other species...no matter how big we think of ourselves we are just another species living on the planet earth.
