Filter observations by time of day

I’m going through sound observations looking for cricket sounds. They call mostly at night, so to make my job easier, limiting observations to between 8 pm and 5 am, for example, would be helpful. I see this as functioning similar to the date range filter. It would apply to both Identify and Observations.

if you’re looking for observations with sounds, you can use the sounds=true filter parameter

That would be a really nice feature. For now we have this project: https://www.inaturalist.org/projects/animals-at-night

This is a great thought. However, a lot of observations have incorrect times (usually from people switching time zones and forgetting to change their camera settings) so searching by time would include some that shouldn’t be included, and exclude some that should. I know this is an issue because a lot of my own photos have the wrong time, and I really try to get it right before uploading but it’s tricky. On my last trip, one of my cameras kept switching back to a different time zone after I changed it - it happened so many times that eventually I just gave up. I think many people don’t worry about it at all.

I know about this option. I use it all the time.

I don’t put in a time at all since I can’t really keep track of the time I took every picture in the field, so I would oppose any change that required a time in order to be RG

Retroactively demoting obs without a time to casual would be extremely destructive, it would render 917 of my observations casual, including multiple range extensions of poorly documented insects

does your camera/phone not automatically record the time for each photo? Issues like those mentioned by @fluffyinca aside, 99.99% of devices I know of automatically date and timestamp images for you when you take them

this is not something that is being proposed here

The camera does but I don’t know of any efficient mechanism to keep that when uploading a large number of photos.

how/why are the photos being stripped of the timestamp when you upload them?

The only way I have to efficiently crop them without losing quality is to screenshot the part I want, the screenshot does not retain the timestamp

I’d be OK with some URL params that could be used this way. The current Filters pop-up is pretty crowded and would need to be redesigned to really fit more options in a useful way.
