.... but found it difficult to find a decent job with just a B.S. in zoology...and I didn't care to go for a masters or higher.
And that can be a big fly in the ointment. Now days the upper wildlife jobs and zoo jobs are going to Masters and Ph.D.'s. No longer is a B.S. the easy in it once used to be. There are more and more people out there with the advanced degrees and that makes it harder and harder to land a job.
When I applied for the zoo job, I was one of several Masters students and there were a couple Ph.D.'s as well. Ultimately, with the combination of low pay and the bad schedule, that list was whilttled down and I was still standing there with open hands. It worked well as I got in and met people and fostered the connections which eventually grabbed me the funding for my Ph.D. When I intereviewed for the zoo job and when the interviews were carried out when I left, the curator did not even interview anyone below a M.S. degree unless you had excellent qualifications.
With my Ph.D. in hand I have applied for several University and Research jobs. MANY of these are highly competitive and it is difficult to find employment. One job in FL had over 90 Ph.D. applicants. Another here in SC had 106 applicatnts...all Ph.D.'s. Hence the reason I find myself going to GA, the job market it difficult and the offers I have received are too tempting to reject.
So, even if you do work up the ladder, with more people receiving degrees the applicant pools are getting larger and you have to do that much more to land the job. Sure, a M.S. or Ph.D. will help you land a job that a B.S. used to get but after working for so long and paying the tuition and now the loans, you don't really want to start on the ground floor. Makes it difficult.
As Lauren said above:
If you got a degree in biology, for instance, you could pretty much walk into a job right out of college. A friend of mine did history and it took him about 6 months or so to find a job after he graduated with his teaching degree.
It will be fairly easy to find a biology job if you are willing to teach K-12. And the higher the grade the easier it will be to find a job. Good middle and high school teachers are few and there are always openings. In my state of SC, within 5 years of starting a teaching job, over 50% of those leave and never come back. I was one of them. I did middle school for two years and left for my doctorate. Our school system has a "critical needs" area and anyone can teach if you have a Bachelors in one of the critical needs. Science was at the top of the list. And....if you are a MALE, this is one of the few jobs where that works FOR you in the selection process. Male teachers in middle and high school are a rare breed and administrators like to see those candidates.
Now...the fact you love reptiles and not tigers has very LARGE benefits. Most reptiles can be privately purchased and you can work with them without having the degrees or the special jobs. (This isn't always an advantage because you get yahoos with giant pythons and dummies with venomous snakes...but I digress). With the love of reptiles you have more independence to work with the species you love and that makes it very satisfying to do it privately and as a hobby. Research oriented systems are a little more difficult to do without the job or degree but there are always projects looking for volunteers and if you really look, it should not be difficult to find a place you can work for free.....I know I've utilized free help on many occasions! Just this past weekend I took a group out to to herp and mammal sampling and had close to 20 people help set the traps and catch the critters.
